History OohMeAccentsSlipping / LiveActionFilms

* Creator/BenicioDelToro in his early role as Dario in the Bond film, ''Film/LicenceToKill'' seems to talk differently in every scene he's talking in....From [[https://youtu.be/r5rUWO1ZUQA?t=7s vaguely Latino]] to [[https://youtu.be/Mn_fWD40hfQ?t=59s "Creepy, greasy, Mexican Stereotype guy"]] to [[https://youtu.be/spBZ99QssXo?t=1m24s "American-ish"]] (del Toro was born in Puerto Rico, spent his adolescence in Pennsylvania and now lives in Spain).

* ''Film/AManOfNoImportance'': for whatever reason, Creator/AlbertFinney is flat-out incapable of pronouncing the "R" sound. Ths makes it a little harder to enjoy his portrayl a an Irish theatre director trying to organise ''rehoouusals''.

** Try watching ''Film/VelvetGoldmine}}'' where he plays an {{No Celebrities Were Harmed}} version of Music/IggyPop. Apparently people from Michigan have the tendency to sound like Creator/SeanConnery.

* The King of Accent Slippage is Creator/SeanBean. His native South Yorkshire accent escapes in virtually all of his movies -- including ''Film/GoldenEye'' where he refers to James in a way that wouldn't be out of place in ''Series/{{Emmerdale}}''. Count Vronski in ''Literature/AnnaKarenina'' wasn't from Sheffield.

* In the Creator/ErrolFlynn Western ''Virginia City'' a Mexican bandit is played by Creator/HumphreyBogart. His accent is not flawless.

* In ''Film/DarkVictory'', Creator/HumphreyBogart delivers the worst FakeIrish accent in the history of the world.

* In ''[[TheSilenceOfTheLambs Hannibal]]'', Creator/JulianneMoore has Clarice's accent for her first few scenes and then drops it for the rest of the movie. Of course, ''Silence of the Lambs'' did establish Creator/JodieFoster's Clarice was trying to lose her Southern accent, but who knew she'd accomplish it so suddenly?
** It's quite glaring in certain scenes.

* Creator/LiamNeeson, usually when he has to say anything with an "oo" sound, like "you". He's become better at it as he's gotten older, but some of his early films like ''Film/{{Darkman}}'' are a fairly {{egregious}} case of this trope.

* In ''Film/WhoFramedRogerRabbit'', Englishman Creator/BobHoskins does a fantastically convincing New York accent for the character of Eddie Valiant (which is strange, as Valiant lives in Los Angeles, but then East Coast is probably an easier accent for the British to do than Californian). It only slips once: when Roger hides in his desk drawer, Eddie screams "GET OUTTA THERE", sounding very British. (It's not the pronunciation so much as the inflection; most Americans would put the emphasis on "outta", but Eddie puts it on "there")

* In the film ''Film/MaryPoppins'', Creator/DickVanDyke puts on a painful cockney accent that comes and goes depending on what scene he's in.

* ''Slate'' critic Dana Stevens [[http://www.slate.com/articles/arts/movies/2013/01/broken_city_starring_mark_wahlberg_and_russell_crowe_reviewed.html has a memorable description]] of how this happens to RussellCrowe in ''Film/BrokenCity'':

* In the ''Film/XMen'' movies, Australian Creator/HughJackman didn't seem to experience accent slippage portraying the Canadian ComicBook/{{Wolverine}}, aside from an odd-sounding vowel here and there (glaring example: near the end of ''Film/X2XMenUnited'' when he says "you don't wanna go that way, trust me"). These seem pretty well impossible to excise from Australian actors (compare to Creator/CateBlanchett, Creator/RussellCrowe, Creator/HeathLedger, etc., especially on O sounds).

*** Another Scot playing a Brit, Ray Park/Toad, had a severe lapse saying "Don't you people ever die?" in the first movie.

* Creator/RachelWeisz's American accent in ''TheFountain'' is, for the most part, passable, but there are moments it goes straight up her nose.

* In ''Film/SupermanTheMovie'', Terence Stamp's Cockney roots can be heard during General Zod's rant, notably when he shouts "....and then one day, your heirs!"

** The eponymous male lead was played quite well by Irish actor Creator/LiamNeeson, but not with the appropriate Cork accent.

* The actors of ''Film/TheShippingNews'' attempted the Newfoundland accent with varying degrees of success. Most distracting, however, was American actress Creator/JulianneMoore's version of it, which usually settled on sounding like a badly-faked Irish accent.

* In the film ''Film/{{Michael Collins}}'', most of the cast are Irish and have according accents. The female lead is Creator/JuliaRoberts, whose accent slips from Irish to Southern twang every time she's on screen, most jarringly in her first scene.

** TheMovie of ''Film/ThePhantomOfTheOpera2004'' is even slippier with Gerard's accent.

* In ''Film/TheBountyHunter'', Scottish actor Creator/GerardButler tries hard to act American, but his accent really slips from time to time.
* Creator/DemiMoore's British accent in ''Flawless'' doesn't really help.

* In ''Film/TheTown'' the English actress Rebecca Hall plays American bank manager Claire Keesey. Her accent subtlely slips throughout the movie, one example being in the scene where her character and Doug (Creator/BenAffleck) are on a date and run into Jem (Creator/JeremyRenner). The line "So I've been telling all my friends about you," is clearly said in a British accent.

* Done intentionally (and cleverly) in the [[Film/{{Watchmen}} film version]] of ''Comicbook/{{Watchmen}}''. Adrian Veidt/Ozymandias, played by Matthew Goode, only speaks with a German accent when in the presence of people he's familiar with- presumably, because he's trying to sound "more American" to the general public.
** This actually came about because the decision to play up Veidt's German background wasn't made until after the first scene in which he addresses the press - for which Goode used a generic American accent -- had already been shot. Nevertheless, the end result is very effective, arguably more so than if Goode had simply spoken with a German twang throughout.
** Goode also occasionally slips back into his native British, giving Ozymandias a grand total three different accents.

* The actors of ''Film/TheShippingNews'' attempted the Newfoundland accent with varying degrees of success. Extremely distracting, however, was American actress Creator/JulianneMoore's version of it, which usually settled on sounding like a badly-faked Irish accent.

** Though the setting is Paris, the film's style is eclectic; therefore, McGregor's accent (or lack of one) may be intentional as he rarely has this problem in other films.

** Practically the entire cast of Doom, all of whom are supposed to be Americans, are British. This may be down to the fact that it was shot in eastern Europe and work permits are easier to get for EU locals. Even Richard Brake, playing Portman, was actually born in the UK (in Wales), though to all intents and purposes he's American. The only American-born American in the entire cast is [[Wrestling/TheRock Dwayne "The Rock" Johnson]]. Creator/RosamundPike is famously English, as are Deobia Oparei (Destroyer), Ben Daniels (Goat), Raz Adoti (Duke), Al Weaver (The Kid), and Yao Chin (Mac - going by the family name Takahashi, his character is supposed to be of Japanese descent, but somehow has three names, which is unknown in Japan). Dexter Fletcher is also in it with a risible attempt at American, but the others seem to do pretty well.

* Creator/AlPacino's accent in ''Film/CarlitosWay'' goes from a slight Puerto Rican accent to normal Pacino accent to Scent of the woman accent.

* Related: in ''Film/TheWorldIsNotEnough'', Creator/JohnCleese is introduced as Q's assistant and Film/JamesBond jokingly calls him "R". Cleese goes by that name in the video games between that and the follow-up ''Film/DieAnotherDay'', in which goes as Q - to which the Irish Creator/PierceBrosnan expressed relief, as couldn't hold his English accent saying "R".

** Mrs. Wormwood's ear-grating [[UsefulNotes/AmericanAccents Long Island Affect]] also fades out at times (Rhea Perlman only has a slight Brooklyn accent in real life).

* Christopher Lambert had trouble being convincing with Connor Macleod's Scottish accent in ''Film/{{Highlander}}'', due to trying to use it on top of his natural French accent.

* In ''{{Volunteers}}'', Creator/TomHanks' bad New English "Haahvahd" accent flips on and off like a lightning bug.

* Basil Rathbone's French accent in ''Film/CaptainBlood'' sometimes gives way to his native [[strike:British]] South African in the middle of sentences.

* In ''Lara Croft: Tomb Raider'', Daniel Craig plays Lara's overtly American rival and slight love interest Alex West. For the most part he does a good job maintaining the accent except for one moment in the temple with the first piece of the film's Macguffin. As he climbs up a ledge you can clearly hear him say in the most British accent possible, "Oh blast!"

* Creator/KeanuReeves gave a not great English accent (with few passable moments) for the first half of or so of ''Film/BramStokersDracula'', but by the end of it the poor fellow seems to have forgotten that Jonathan Harker was ''not'' raised in Canada (he was born in Beirut, Lebanon and raised in Toronto).

*** Same goes for ''Film/TheDevilsAdvocate'': he seemingly arbitrarily alternates between his natural accent and a Southern-sounding accent (the latter being more appropriate for his character). As with ''Film/BramStokersDracula'', he basically abandons the second accent about halfway through.

* Creator/JenniferLawrence and Josh Hutcherson in Film/TheHungerGames occasionally speak with their native Kentucky accent. However, this is completely logical since District 12 is supposed to be in the Appalachian coal-producing region, i.e. Kentucky and West Virginia, and this may in fact have been intentional on the part of filmmakers.

* Part of [[TheReveal the Reveal]] in the movie Gotcha! While argue about whether she used him or not, Sasha's accent slips and drops completely when she admits she isn't from Czechoslovakia.

* [[Creator/SebastianStan Sebastian Stan]] has mostly done away with his original Romanian accent, but you can hear it very slightly in ''The Education of Charlie Banks'' when he says "I'm way too hungover for a lecture" right before [[spoiler:Mick (Jason Ritter) beats him up]].
* In ''Film/JackBrooksMonsterSlayer'', the hick protagonist frequently slips back into the actor's native Canadian accent when agitated.
* In ''Film/JasonBourne'', Creator/AliciaVikander's Swedish accent slips out frequently as she plays American Heather Lee.

* In ''Lara Croft: Tomb Raider'', Daniel Craig play's Lara's overtly American rival and slight love interest Alex West. For the most part he does a good job maintaining the accent except for one moment in the temple with the first piece of the film's Macguffin. As he climbs up a ledge you can clearly hear him say in the most British accent possible, "Oh blast!"

* In ''Film/Lara Croft: Tomb Raider'', Daniel Craig play's Lara's overtly American rival and slight love interest Alex West. For the most part he does a good job maintaining the accent except for one moment in the temple with the first piece of the film's Macguffin. As he climbs up a ledge you can clearly hear him say in the most British accent possible, "Oh blast!"

* Creator/RobinWilliams adopts the guise of an old British nanny in the movie ''Film/MrsDoubtfire''. To North American viewers his accent is flawless, but a genuinely British character is confused by his accent and asks him where in England he comes from, as his accent is all over the place. Williams's character hastily improvises to say he's from everywhere, moving all around the country growing up and adopting bits of the local accents as he went.

** It's {{lampshade|Hanging}}d in the film. Ben (NicolasCage) asks about her accent--"Pennsylvania Dutch?"
