An outer-space mission to save mankind, the inner thoughts of Stephen Hawking and the dystopian rage of Katniss Everdeen are all heading to movie theaters this fall. If there's a dominant theme in this season's lineup, it's an ongoing obsession with science and technology, be it fictional ("Interstellar," in which Matthew McConaughey takes one giant leap) or real ("The Imitation Game," about the godfather of modern computing, Alan Turing). Perhaps somewhere in between is Jason Reitman's drama "Men, Women and Children," about social interaction in the Internet age.
This eclectic fall season offers some old-fashioned fare, too, including an unusual number of mystery-thrillers, most notably David Fincher's "Gone Girl," starring Ben Affleck as a could-be killer, but also "The Judge," with Robert Downey Jr., and "Before I Go to Sleep," with Nicole Kidman. Rounding out the roster are animated features ("The Penguins of Madagascar"), self-improvement stories ("Hector and the Search for Happiness") and Oscar hopefuls such as the drama "Foxcatcher," starring an against-type Steve Carell.
And, finally, the 20-year wait for "Dumb and Dumber To," the comedy sequel starring Jim Carrey and Jeff Daniels, is over.
