The Perks of Being a Wallflower actress Emma Watson appeared on The Late Show with David Letterman last night to discuss her new film by Stephen Chbosky.

Watson talked about filming in New Orleans for End of the World and how she’s recently been in Iceland for Noah. The Iceland conversation turned into a funny bit about the diet she’s had there which has included food like whale and reindeer.

They then spoke about Perks filming in Pittsbugh, and Watson told a funny story about the crew taking over an entire hotel which led Dave to imply there were some big adult parties happening.

The actress began wrapping up the appearance by updating viewers on her time at Brown University where she said she’s been mostly taking English-major classes.

At the end, a new clip from The Perks of Being a Wallflower aired. It was from the end of the film where Charlie (Logan Lerman) and Sam (Watson) discuss relationships and why people stick with the wrong people.

Watch below! Perks hits theaters September 20 in New York and Los Angeles. Hypable will be at the premiere next week to pose questions to the cast.

Note: Perks clip begins at 11:15.
