In an interview with New York Magazine, "Get Him to the Greek" director Nick Stoller spoke about working with Diddy and teaching him about improv.

Tell me about Diddy. He was my favorite part in the movie; who knew he was so funny! (Besides for him, that is.)

When I was writing the script. I thought of him as that part [a hard-nosed, maniacal record exec]. And he came in to audition, and I really hoped he’d be good, and he was amazing — hilarious. He has a crazy energy that has been untapped for the most part. The guy doesn’t sleep, which is interesting. It took him a little while to get used to the idea of improv, but once we’d loosen him up, he’d be so funny. There’s a scene in the movie with Diddy and Pharrell, and Pharrell was kind of getting his bearings on set, and Diddy goes, “Oh, yeah, we do a lot of improv here.” And I was like, I can’t believe Sean Combs just said, “We do a lot of improv.” I've turned Sean Combs into a comedy nerd!
