In the upcoming comedy, Efron plays a frat boy who disrupts the family life of his neighbors (Seth Rogen and Rose Byrne). Rogen, 31, shared with Us Weekly at the Hilarity for Charity event on Apr. 25 that Efron really is as good looking in person as he appears on film.
"I did a scene next to him, and we're both shirtless, and it was a very humbling experience," he added. "I marveled that we're literally the same species. He's very veiny. I'm not that veiny . . . and I'm hairier than he is."
