Seyfried, 27, said she had to get intimate with multiple male co-stars including Peter Sarsgaard and Adam Brody in the film, reported Us magazine.
"I don't want my dad to see my naked body ever. I'm going to sit through (the screening) tonight and cover his eyes. It's really only the nudity.
"I don't have problems with him seeing me in violent situations. In sexual situations, it's a little tough, but it's more just the nudity. I think anybody can relate to that," she said.
