The Time Traveler's Wife is a 2009 American romantic science fiction drama film based on Audrey Niffenegger's 2003 novel. Directed by Robert Schwentke, the film stars Eric Bana, Rachel McAdams, and Ron Livingston. The story follows Henry DeTamble (Bana), a Chicago librarian with a paranormal genetic disorder that causes him to randomly time travel. He tries to build a romantic relationship with Clare Abshire (McAdams), whom he meets when she is a child, and who later becomes his wife.

The filming began in September 2007, originally in anticipation of an autumn 2008 release. The film's release was postponed with initially no official explanation from the studio. McAdams later noted that the delay was due to additional scenes and reshoots that could not be completed until the season at their outdoor location matched previously filmed footage, and Bana had regrown his hair following his work on the 2009 film Star Trek. Produced by New Line Cinema, the film was released on August 14, 2009, by Warner Bros. Pictures to mixed reviews but was a commercial success.
