If all goes according to Warner Bros.' plans — and we know how flexible those can be — the final Harry Potter movie will debut on July 15, 2011. Other films on the studio's release calendar include an adaptation of Sherlock Holmes starring Robert Downey Jr. and Jude Law set for Christmas Day of this year, a big-screen version of the DC Comics superhero Green Lantern scheduled for December 17, 2010, and the, uh, charmingly titled Robin Williams vehicle A Couple of Dicks, which is due in theaters on January 29, 2010.
