Even the stars of The Magicians can't help but get starstruck when encountering The Magicians author Lev Grossman.

"I think I was having a fitting when we were doing the pilot in New Orleans and Mike Cahill, the director, casually was like, 'Oh, hey. This is Lev,'" recalls star Hale Appleman, who plays Eliot. "And I had a moment."

Who makes Appleman's Magicians co-stars Summer Bishil, Arjun Gupta and Olivia Taylor Dudley starstruck? Find out in the video above.

The Magicians airs Mondays at 9/8c on Syfy.
