If the success of "Avatar" and "Alice and Wonderland" haven't made it clear already, 3D is blowing up on the big screen. "Hubble 3D" is a must-see for anyone obsessed with the movie technology and/or outer space. Narrated by Leonardo DiCaprio, the film features stunning footage shot by the IMAX 3D cameras that joined the crew of the space shuttle Atlantis when it went up to fix the Hubble in 2009. It also features images the telescope has captured during its nearly two decades in space. You'll be gripping your seat during the spacewalks and 3D flight through the universe. Embrace your inner child, sit back, and enjoy the ride. Opens March 19.
