About Time is a British romantic comedy science fiction film revolving around time travel. Written and directed by Richard Curtis, the film is based on his own screenplay and stars Domhnall Gleeson, Rachel McAdams and Bill Nighy. The film was released in Britain and Ireland on September 3, 2013 and was released in the United States on November 1, 2013.Tim Lake finds out from his father when he's 21 that every male in his family has the ability to travel in time. At first the awkward Tim uses it to improve his life and impress the girl of his dreams, Mary. But when he accidentally erases part of his timeline, he learns about the ramifications causality can have on his life.
Costume Test Montage: Where Tim watches Mary try different dresses for her dinner with the bestselling author. The very first dress turns out to be the winner. The whole scene could be seen as an allegory for the revisions Tim is going through with his life.
"Groundhog Day" Loop: While the setup would lend itself to this, Tim doesn't replay many events repeatedly. But he does loop over his choice of best man quite a few times, with each candidate giving a worse speech than the last.
Out of Time, Out of Mind: Averted. Tim is definitely changed by falling in love with Mary, and treats losing that as losing a central part of his life.
Peggy Sue: Tim does this deliberately to avoid embarrassment.
Power Perversion Potential: Tim doesn't seem to particularly revisit his sex scenes with Mary apart from the first. Though considering any one of those encounters could have lead to a child, alter the timeline and erase his current children, perhaps this is merely caution on his part. Tim also rejects the chance abuse his power to cheat on his girlfriend, despite knowing full well he can make it so it never happened.
Ret Gone: After changing his sister's life, Tim's daughter is replaced by a son. He brings her back by retgoning the son.
Ripple-Effect-Proof Memory: Only the person who makes the trip back in time possesses this. Tim's dad is a time traveler too, but doesn't remember the changes Tim makes.
At one point Tim travels back with his sister (who can't travel back in time on her own). When they return to the present her memory is affected (she suddenly knows she is in a different relationship in the altered timeline) but she also retains the knowlege they time travelled in the first place.
In one conversation with his dad, Tim guesses that his dad may also have gone back and replayed it, and his dad confirms this. One wonders what'd happen if Tim and his dad really wanted opposite things from a conversation: would they both keep replaying it, flip-flopping the outcome, ad infinitum?
Probably not. They would likely recognize the other's saying "Excuse me a minute," and call them out on it.
Second Love: Tim is first infatuated with his sister's boyfriend's cousin Charlotte, from whom he learns an important lesson: "All the time travel in the world won't make someone love you." It works out with Mary because they have actual chemistry without time travel.
Secret Keeper: Tim reveals his secret to his sister and actually takes her back time travelling with him. She only knows briefly however; due to other circumstances Tim ends up reverting this edit to the timeline.
Suspiciously Apropos Music: The chorus of Nelly's song "Delima" plays when Tim spots Mary at the party: "No matter what I do, all I think about is you..."
Timey-Wimey Ball: The time travel appears to have at least two different modes, but the explanation is very scanty. Tim can go back to a previous occasion and change what he did, but then he can choose to either live from that point onwards, or snap forward to where he jumped from and see what the changes have been. The event described in Secret Keeper seems to suggest he can also undo these changes.
Trailers Always Lie: The trailer suggests that Tim and Mary's entire relationship is eradicated from the timeline, but actually it's only their first meeting.
Furthermore, the trailer gives the impression that he erases their meeting by going back in time to prevent his father from dying in a car accident. In fact, it's his sister, not his father, who's involved in a (non-fatal) car accident, and it happens much later in the movie. His father does eventually die, of lung cancer, but there's nothing he can do to prevent it.
Wacky Marriage Proposal: Subverted. Mary thanks Tim for not staging one, and Tim agrees... and then goes outside to dismiss the one he actually did stage.
