Seth Rogen kicked off the premiere of his comedy The Interview by thanking Sony Pictures Entertainment co-chairman Amy Pascal for having the courage "to make this movie".
Rogen addressed the audience before the packed screening in downtown Los Angeles.
The film about an assassination attempt on North Korean leader Kim Jong Un has taken centre stage in the wake of the cyberattack on Sony. Some have speculated that North Korea was behind the attack in retaliation for the upcoming movie.
Sony prohibited interviews at the premiere and postponed a press junket for Wedding Ringer scheduled on December 13. The comedy stars Kevin Hart, who fired back on Instagram after being called a "whore" in a leaked Sony email.
Pascal apologised for other leaked emails containing racially offensive jokes about President Barack Obama.
