Ben Affleck reportedly considered himself a “serious actor” after kissing another man in the film Chasing Amy.

Director Kevin Smith was speaking at a 20th-anniversary screening of 1997 indie hit Chasing Amy at LGBTI festival Outfest in Los Angeles when he revealed that Affleck and co-star Jason Lee initially felt uneasy about their on-screen gay kiss.

According to Gay Star News, Smith recalled how Affleck said that “a man kissing another man is the greatest acting challenge an actor can ever face,” and that once cameras had stopped rolling, he stated, “now, I'm a serious actor.”
