Even after weeks of promoting Universal’s “Oblivion” around the world, Tom Cruise showed why he’s still is a movie star. On April 10, at L.A.’s Dolby Theater, Cruise arrived at 5 p.m., two and a half hours before the film screened, to sign autographs and take pictures with fans.

He was later joined by director Joseph Kosinski, producer Peter Chernin and co-stars Morgan Freeman, Andrea Riseborough and Melissa Leo.

Kosinski said he knew he’d need a star to get this film off the ground, but he also needed a talented thesp.

“I knew, given that it was an original science-fiction film with no recognizable brand, that I would need a movie star,” he said. “With Tom I got that star who was also a great actor, and that is the thing about this film, given all the elements involved with how the story is told. It really shows how great an actor Tom is.”

Also on hand for Wednesday’s premiere were NFL superstar Robert Griffin III, U execs Donna Langley and Ron Meyer and producer Mark Burnett.

Post-screening, the “Oblivion” team partied at the Ray Dolby Ballroom.
