Rachel McAdams made a triumphant return to the red carpet this week for the London and Munich screenings of About Time. On Saturday she wore a short black Saint Laurent dress to the Munich event and joked around on the red carpet. At Thursday's London premiere, she wore a floor-length Roksanda Ilincic gown and debuted a fiery red hair color at the event, where she posed with her costars Domhnall Gleeson and Margot Robbie, as well as the film's director, Richard Curtis. It's the first time we've seen Rachel out and about on the press trail since this April, when she promoted the romantic drama To the Wonder in LA. Her latest project is a British-based romantic comedy and science fiction movie — it focuses on a young man, played by Domhnall, who tries to change his past to have a better future. It's not the first time Rachel has taken on the time-travel theme in a film, as she starred in The Time Traveler's Wife alongside Eric Bana in 2009.
