Leonardo DiCaprio to star in Christopher Nolan’s ‘Inception’ Leonardo DiCaprio has signed on to star in Inception, the first post-Dark Knight film for director Christopher Nolan. The contemporary story is described as taking place within “the architecture of the mind.” Nolan set up the project less than a month ago at Warner Bros., the studio where he made his Batman films as well as the thriller “Insomnia.” The filmmaker and the studio are aiming for a 2010 release. DiCaprio next appears in Martin Scorsese’s “Shutter Island.”
