The actress would star alongside Bradley Cooper and Emma Stone.
Details of the film, such as little things like plot and characters, are being kept under wraps, but given that its Crowe behind the camera, the soundtrack should include lots of great rock songs from the 1970s and '80s. This is, after all, the man who unearthed great tracks from the likes of the Beach Boys, Peter Gabriel and Tom Petty for previous films like "Vanilla Sky" and "Almost Famous."
McAdams is currently starring in Terrence Malick's "To the Wonder" and will next appear in the time-travel comedy "About Time."
Deadline first reported that McAdams was in talks for the role.
