In an interview with Parade.com, Seth Rogan says that it was his idea to cast actual porn stars in supporting roles for his new hit movie, Zack and Miri Make a Porno.

“I get credit for that,” he tells Parade.com about suggesting going with real XXX starlets to director Kevin Smith. “I don’t often give the director creative advice, but I told Kevin– ‘Please just hire real porn stars because otherwise it will just be so awkward.’”

His advice led to porn star Katie Morgan and adult entertainment legend Traci Lords being added to the cast that includes Rogan, Elizabeth Banks and Jason Mewes.

“To Katie (Morgan) it was easy,” Rogan told Parade.com. “All she had to do was take off her clothes and pretend she was having sex. It was a dream job for her. By the way, Katie is super cool. She’s a lot smarter than I am. She’s like a MENSA member.”

Rogan also talked about his living situation getting in the way of his ability to fully research his latest role. “I live with my girlfriend, so that kind of tempers my porn watching, or makes it occur at odd hours,” said Rogan. “You know it’s like five minutes here, eight minutes there. You kind of learn to make do. That’s not to say that I have watched a lot of porn films in my time.”
