About Time Cast and Characters

Tim Lake (Domhnall Gleeson) is a young man from Cornwall. He grows up in a house by the sea with his father (Bill Nighy), his mother (Lindsay Duncan), his absent-minded maternal uncle (Richard Cordery), and his free-spirited sister, "Kit Kat" (Katherine, played by Lydia Wilson). At the age of 21, Tim learns that the men of his family have a special gift: the ability to travel in time, subject to one constraint: they can only travel to places and times where they have been before. After his father discourages Tim from using his gift to acquire money or fame, he decides that he will use it to improve his love life.

The following summer, Kit Kat's friend Charlotte (Margot Robbie) visits. Tim is instantly attracted to her but waits until the end of her stay to tell her how he feels. She tells him that he should have told her earlier so that something could have happened between them. Tim travels back in time and, the second time around, tells Charlotte in the middle of the holiday how he feels. In this instance, Charlotte says that it would be better to wait until the last day of the holiday. Heartbroken, Tim realises that Charlotte is not interested in him and that time travel will not help him to change her mind.

After the summer, Tim moves to London to pursue a career as a lawyer. He is put up by his father's old acquaintance, Harry (Tom Hollander), a misanthropic playwright. After some months, Tim visits a Dans le Noir restaurant, where he meets Mary (Rachel McAdams), an American who works for a publishing house. They flirt in the darkness of the restaurant, and afterward, Mary gives Tim her phone number. Tim returns home to find a distraught Harry, the opening night of whose new play has been ruined by one of the actors forgetting his lines at a crucial point. Tim goes back in time to put things right and the play is a triumph.

Tim tries to call Mary, but discovers that her number is no longer in his mobile phone. By going back in time to help Harry, Tim chose a path in which the evening with Mary never happened. However, he recalls that Mary was obsessed with Kate Moss. By attending a Kate Moss exhibition, he is able to run into Mary again, but discovers she now has a boyfriend. Tim finds out when and where they met, turns up early and persuades her to leave the party before she can meet her future boyfriend. Their relationship develops and Tim moves in with Mary. He encounters Charlotte again, and this time she seems interested in pursuing a relationship with him. Tim turns her down, realising that he is truly in love with Mary. He proposes marriage; she accepts and they have a daughter, Posy. Kit Kat's unhappy relationship, failure to find a career, and drinking lead her to crash her car on the same day as Posy's first birthday.

While Kit Kat is recovering, Tim decides to intervene in her life and prevents her from meeting her boyfriend, Jimmy (Tom Hughes). When he returns to the present, he finds Posy has never been born and that he has a son instead. His father explains that travelling back to change things before his children were born would mean those children would not be born. Events that occurred before Posy's birth cannot be changed, and Tim must accept the consequences as a normal person would. Tim accepts he cannot change Kit Kat's life by changing her past but he and Mary help her to change in the present. She settles down with Jay, a friend of Tim's, and has a child of her own. Tim and Mary have another child, a baby boy.

Tim learns that his father has terminal cancer and that time travel cannot change it. His father has known for quite some time, but kept travelling back in time to effectively extend his life and spend more time with his family. He tells Tim to live each day twice in order to be truly happy. The first time with all the tensions and worries that keep us from noticing how sweet the world can be, but the second time noticing. Tim follows this advice and also travels back into the past to visit his father whenever he misses him.

Mary tells Tim she wants a third child. He is reluctant because it means he will not be able to visit his father again. Tim tells his father that he cannot visit any more, and they travel back to Tim's early childhood, reliving fond memories. Mary gives birth to a baby girl, and Tim knows he can never see his father again. Tim comes to realise that it is better to live each day once, and appreciate everything as if he is living it for the second time. The film ends with Tim leaving Mary in bed and getting his three children ready for school.
