A 1990 SliceOfLife RomanticComedy film directed by Herbert Ross, written by Creator/NoraEphron, and starring Creator/SteveMartin, Creator/RickMoranis, and Creator/JoanCusack.

Vincent "Vinnie" Antonelli (Martin) is a wise-cracking, flashy ex-mobster who has entered the Federal Witness Protection Program and is adjusting to {{suburbia}} with the help of Barney Coopersmith (Moranis), an FBI agent assigned to protect him, whose wife just left him for her own selfish reasons.

When Vinnie gets into trouble for committing some local crime, he gets arrested by local District Attorney Hannah Stubbs (Cusack), who is not at all happy that someone like him is being under the watch of Barney and vents at the FBI agent when they first meet. The reason for all of Hannah's frustration is because she's a divorced mom stuck raising her two sons.

But as the movie progresses, [[CharacterDevelopment Vinnie learns to shape up]], and [[AwLookTheyReallyDoLoveEachOther Barney and Hannah realize their feelings for each other.]]

!!This movie provides examples of:

* BadLiar: Vinnie is a ConsummateLiar who can say anything with a straight face, but he's not always very good at coming up with the lies themselves. "Why do you need 25 copies of it?" "In case I want to read it more than once!"
* BavarianFireDrill: Vinnie talks Barney into handing over his wrinkled suit trousers so he can take them downstairs to get pressed, treating it as SeriousBusiness, when his actual plan is to give his F.B.I. handler the slip. Barney stands alone in his boxers for a moment before realizing that he's been had.
* BelligerentSexualTension: Shown between Barney and Hannah when they first meet.
* BilingualBonus: Vinnie's (probably fictional) dog is named "[[GettingCrapPastTheRadar Vaffanculo]]." Hannah's reaction to this indicates she not only understood it, but provides context for the audience that this was Not A Nice Thing To Name A Dog.[[note]]It basically translates to "Go do it in the ass."[[/note]]
* BlastingItOutOfTheirHands: Despite claiming that he DoesntLikeGuns, Vinnie proves to be quite the sharpshooter when dealing with the two hit men:
-->''<hands back Barney's revolver>''
-->'''Barney:''' "I thought you said y--"
-->'''Vinnie:''' "''ILied.''"
* BlatantLies: Vinnie is pretty shameless about stating obvious lies with a straight face.
* CharacterDevelopment: Vinnie becomes more responsible and it's implied he really does come to love and care about the town. Barney loosens up and learns to enjoy his life; Hannah does the same.
* ComedicUnderwearExposure: Happens to Barney when Vinnie rebels yet again while they stay at a New York hotel.
* CreatureOfHabit: Barney starts as this, to the point that his wife leaves him because he never changes anything about his routine and is not fun anymore.
* DisgustingPublicToilet: Vinnie doesn't like to use public toilets as shown in two scenes.
* DistractedByTheSexy: Vinnie in the grocery store when he sees Chaldean.
* EmbarrassingNickname: While undercover as someone from Vancouver, Barney is unfortunate enough to get the nickname of "Dicky", much to his dismay.
-->'''Barney:''' Call me "Dicky" one more time, and I'll kill you.
* EvenEvilHasStandards: When Vinnie's put on the stand, the cross examination tries to discredit him by pointing out all the perks of being in Witness Protection. Vinnie then continues by pointing out he also never gets to see his parents or friends again and that his wife left him. He finishes by saying it's true that he's only saying these things because of the government deal -- but he gave his word that he'd tell the truth, and that's what he's doing.
** Of course since Vinnie is a ConsummateLiar, you have to take everything he says with a grain of salt.
* EveryoneChasingYou: The movie's climax following the escape from the courtroom.
* FakeRealTurn: Vinnie gets bored with life as a suburbanite, so he begins a scam that involves getting donations of loose change to "renovate the little league park." At first he plans on just pocketing the money and getting out of town. By the end of the movie, not only does the local little league team have a new place to play, Vinnie is coaching them.
* HereWeGoAgain: The pair of hitmen sent to kill Vinnie end up in Witness Protection as well. They even live in the same town and have married Vinnie's first and second wives.
* KarmaHoudini: Vinnie is a criminal who has no real remorse and continues to commit crimes on a daily basis... and is voted the Man of the Year.
* LightBulbJoke[=/=]SoUnfunnyItsFunny: "What's the difference between a light bulb and a pregnant woman? You can unscrew a light bulb."
* MarryThemAll: Vinnie has three wives over the course of the movie. And not a single divorce.
* RunningGag: Barney never seems to remember to unfasten his seat belt before trying to get out of the car. [[RuleOfThree On the 3rd and final time]], he becomes aware of this habit.
* SharpDressedMan: Vinnie loves his shiny suits, and makes sure Barney gets one, too. His Little League coach's outfit is even a nice suit in the team colors, complete with baseball pinstripes.
* StraightManAndWiseGuy: Barney and Vinnie
* SuperOCD: Barney is implied to have this, particularly when he eats pancakes.
* WitnessProtection: The whole premise is how much trouble Vinnie has in dealing with the new lifestyle required by the program.
