'Gravity' (October 4)
Cast: Sandra Bullock, George Clooney
Director: Alfonso Cuaron ("Harry Potter and the Prisoner of Azkaban"; "Children of Men")
What to watch for: Originally due in 2012, this mysteriously delayed sci-fi epic has maintained strong buzz about its supposed breakthrough use of technology and awe-inspiring visuals (set to be released in IMAX and 3D) in a tale of two astronauts stranded in space. Film fans would expect nothing less from Cuaron.
