''Due Date'' is the heartwarming story of two guys traveling together on a journey that will, in the end, help them both to learn more about themselves.

And if you believe that, we have a bridge we'd like to sell you.

''Due Date'', starring Creator/RobertDowneyJr and Zach Galifianakis, is a comedy about two men trying to get to Hollywo...er, Los Angeles. Peter Highman (Downey) is a rather [[HairTriggerTemper low-tempered]] man, because his wife Sarah (Michelle Monaghan) is about to give birth and he is trying to get back to Los Angeles in time for it and figure out what to name his soon-coming child. He meets Ethan Tremblay (Galifianakis) and soon gets almost arrested twice, shot by a rubber bullet and put on a No-Fly list due to using the words "bomb" and "terrorist," all thanks to being near Ethan. To make up for it, Ethan gives Peter a lift because he is going to Hollywood to become an actor. Ethan also has an interview around the same time as Peter's wife's delivery. Making the trip more difficult is the fact that Ethan seems to have never grown up and wanting to go to the Grand Canyon, Peter's inability to relax and the fact that Ethan seems unable to rub two brain cells together.

Will they make it in time?

!!Provides examples Of:

* ActorAllusion: Peter has never taken drugs before (or so he claims).
** And the way he looks when [[spoiler:he and Ethan ''finally'' arrive at the hospital]] brings to mind Creator/RobertDowneyJr as Film/SherlockHolmes.
** Zach Galifianakis plays a ManChild LethallyStupid FatIdiot [[spoiler:who actually started the whole mess]]. Sounds like [[TheHangover Alan]].
* AmazingFreakingGrace: A version by Creator/RodStewart on the soundtrack.
* AmbiguouslyGay: Ethan, very, ''very'' much. In the Italian version, he is even dubbed with a very CampGay voice.
* AshesToCrashes: Though these ashes were enjoyed as coffee.
* AsYouKnow: Parodied during Ethan's acting exercise.
--> '''Ethan''': (''in character'') As you know, I'm your fiance. I have terminal cancer.
* BadBadActing: When Ethan is challenged to act out scene prompts, he just repeats the prompt.
* BirthDeathJuxtaposition: Sort of. Peter's journey is right before the birth of his child and Ethan's is right after the death of his father.
* BlackBestFriend: Peter's friend Darryl, played by Jamie Foxx (who happens to be Creator/RobertDowneyJr's real-life friend; they co-starred in ''TheSoloist''). In a possible parody of the MagicalNegro idea, the first half of Darryl's appearance is essentially him guiding Peter to do the right thing and help Ethan; then, after an extremely short period of time, he ends up kicking Ethan out of his house himself (to which Peter is extremely sympathetic).
* BlackComedy
* BookDumb: Ethan. For example, he thought the Grand Canyon was in Texas and that it was artificial. Peter corrects him, saying it's in Arizona and that nature carved it.
* [[BreakTheCutie Break The Dummy]]: After getting his arm broken, Peter absolutely snaps on Ethan and tears him a new one on so many levels.
* BreakTheHaughty: Every moment Peter spends in Ethan's company.
* BrickJoke
--> '''Ethan''': What are you, some kind of girl or something?
* ButtMonkey: Peter, Peter, Peter. Note that only ''some'' of it is actually deserved. (''Heavy'' crossover with JerkassWoobie.)
* CloudCuckoolander: Crosses with BookDumb and TheDitz for Ethan.
* ComicallyMissingThePoint / MathematiciansAnswer:
-->'''Peter''': Why...are your father's ashes...in a coffee can, Ethan?
-->'''Ethan''': Because he's ''dead'', Peter!
* DeadpanSnarker: Peter
* TheDitz: Quite often, Ethan acts in a ''cosmically'' stupid manner.
* DuelingStarsMovie
* EasilyForgiven: Ethan. [[spoiler:Even when Peter kicks his ass for having had his wallet the entire time, that's a sheer fraction of what Ethan deserves.]]
* EmpathicEnvironment: It's raining as Ethan breaks down crying during the last scene prompt.
* FatIdiot: Ethan
* {{Foreshadowing}}: [[spoiler:In the first scene of the movie, Peter describes a bizarre dream to his wife about a bear cutting his child's umbilical cord and the fact that, in the dream, he was alright with it. Guess who cuts the umbilical cord at the end of the movie?]]
** [[spoiler:There's a scene in the middle of the film where Peter gets a contact high from riding in the car with Ethan while he's smoking weed. At one point, he looks over at Ethan and sees a bear, further driving the point home.]]
* HairTriggerTemper: Peter
* HandicappedBadass: [[spoiler:The counter of the Western Union.]]
* HiddenHeartOfGold: Peter may seem incredibly mean-spirited at times, but he shows plenty of signs that he's actually a good guy, namely not ditching Ethan's father's ashes on the side of the road and comforting Ethan on more than one occasion as he tries to deal with the loss of his father.
** Arguably, Ethan fits this (since his {{Jerkass}}ery is mostly attributable to being an overgrown child and he is almost always well-intentioned).
* HilariousOuttakes: Like you wouldn't [[http://youtu.be/iKifh20ZIbA believe]].
-->'''Robert Downey Jr.''': (''jokingly'') Fuck, I'm surrounded by ''dickheads''!
* HumiliationConga: The whole road trip for Peter.
* JerkWithAHeartOfGold: Peter
* TheJinx: Ethan
* JugglingLoadedGuns: Just when you think things couldn't get any worse, Ethan accidentally shoots Peter in the leg.
* KarmaHoudini: Surprisingly, Ethan never gets arrested for smoking pot or [[spoiler:stealing a deportation officer's van to "rescue" Peter]]. In fact, he is actually rewarded by eventually getting to [[spoiler:appear on ''TwoAndAHalfMen''.]] Every single thing negative consequence of his actions lands on Peter instead.
* LethallyStupid: Ethan. Ethan! Ethan!!! E-T-H-A-N.
* ManChild: '''Ethan'''. He couldn't be more immature if he was an actual teenager. Peter has some emotional problems as well, although stress could explain both their issues (although since Ethan's the one causing most of the stress...).
* [[ManicPixieDreamGirl Manic Pixie Nightmare Dude]]: Also Ethan.
* MarijuanaIsLSD: The trippy scene when Ethan is smoking in the car.
** [[JustifiedTrope Justified]] in that Peter was also high on Vicodin at the time.
* TheMillstone: Ethan
* MoodWhiplash: Several times. The most jarring ones are when Peter challenges Ethan to act and he fails horribly until he asks him to play a football coach whose wife wants a divorce and Ethan ends up crying for real as it makes him think about his father; the second one is after [[spoiler:Darryl accidentally makes coffee out of]] his father's remains but Ethan drops the ashes while trying to recover what's left, and ends up sobbing on the carpet while Peter comforts him.
** Also from the heartwarming scene of scattering Ethan's dad's ashes to [[spoiler:Peter beating Ethan up for having his wallet the whole time]].
* [[TheMountainsOfIllinois The Mountains Of East Texas]]: A shot shows the car passing a sign that says "Dallas - 36 miles." Cut to Peter and Ethan talking in the car with [[TheyJustDidntCare mountains passing in the background]].
* OnlySaneMan: Peter. Aside from Ethan, everyone else that he encounters also seems to be a bit mentally off-kilter, other than his own wife and his friend.
* ParentalSubstitute: Peter is significantly more mature than Ethan and often provides fatherly comfort for him during their trip, particularly in two scenes--when Ethan accidentally drops the ashes on the carpet and breaks down, and when he convinces Ethan to spread his father's ashes [[spoiler:in the Grand Canyon]].
* PlotHole: The film doesn't explain how Peter and Ethan got back into the United States driving a [[spoiler:stolen Mexican cop car]] ''and'' without Peter's ID.
* RaceAgainstTheClock: The final desperate drive to get to Los Angeles in time to see Peter's baby born.
* RantInducingSlight: After getting put on a no-fly list; being forced to travel with Ethan, the guy who got him put on the list, and trying without success to get money transferred from his very pregnant wife, Peter explodes at the [[spoiler:Western Union employee. Said employee turns out to be a handicapped Iraq War veteran who trounces Peter.]]
** And if that wasn't bad enough, [[spoiler:Peter later finds out that Ethan had his wallet the whole time and kept it from him just so they would travel together. Peter responds by slamming Ethan's face into the truck and trying to strangle him]].
* TheReasonYouSuckSpeech: "I despise who you are at a cellular level."
* [[RepurposedPopSong Repurposed Hip-Hop Song]]: {{Ice Cube}}'s "Check Yo Self" was used in a lot of commercials. Usually around the part when Ethan quotes the song.
* RoadMovie
* ShapedLikeItself: "Dad, you were like a father to me..."
* SpiritualSuccessor: To ''TheHangover'', from the same director, and to ''PlanesTrainsAndAutomobiles'' as both films feature an OddCouple traveling cross-country together.
* StockScream: A WilhelmScream as Peter and Ethan are hurtling through a construction zone.
* TooDumbToLive: Ethan. He's nearly too dumb for [[CosmicPlaything Peter]] to live.
* UnfortunateNames: [[spoiler:Ethan names Peter's daughter Rosie. "Wait, 'Little Rosie Highman'?"]]
* VitriolicBestBuds
* WhatTheHellHero: Ethan [[spoiler:hiding Peter's wallet because he didn't want to be alone]].
* WholePlotReference: Many reviews called it a mean-spirited version of ''PlanesTrainsAndAutomobiles''.
* WhyDoYouHateTheDog: Though more aware of how annoying the dog is than usual, it's still played straight.
* WouldHurtAChild: Peter, fairly mildly. It's played for an odd mix of shock, laughs and [[EstablishingCharacterMoment character development]].
* YankTheDogsChain
* YoungerThanTheyLook / OlderThanTheyLook: Ethan claims he's 23. [[spoiler:He later admits it's not true, but he doesn't say how old he is.]]
