Rachel McAdams is in talks to star in Richard Curtis' 'About Time'.
The 33-year-old actress would play the "dream girl" to Domhnall Gleeson's male lead in the picture, which would be the second time Rachel has taken a starring role in a movie about time travel.
Zooey Deschanel was once attached to the role but is thought to no longer be involved.
Bill Nighy, Vanessa Kirby, Tom Hollander, Lydia Wilson and Margot Robbie are all signed on to star in the picture.
Production is set to begin on 'About Time' in London in June.
Tim Bevan, Eric Fellner, Liza Chasin and Amelia granger are producing the film.
Rachel - who most recently starred in surprise hit 'The Vow' alongside Channing Tatum - has a number of projects in the pipeline including thriller 'Most Wanted Man', and will also appear in theatres in Terrence Malick's as-yet-untitled project alongside Javier Bardem, Ben Affleck and Rachel Weisz.
