Clark Duke is an American actor, writer and producer. He co-created the web comedy show Clark and Michael with his partner, Arrested Development star Michael Cera, which was later picked up by CBS and turned into a television series.

He also has a supporting role in the upcoming teen comedy film Superbad.

Dale is portrayed by Clark Duke in the ABC Family’s upcoming comedy series on college life, Greek. A religious and bespectacled nerd from Texas, he’s part of the same engineering honors program as Rusty, with the two roommates getting along in being geeks. Dale’s thinking is typically in black-and-white, with no room for anything in between, partly due to his religious upbringing. Not at all the type of mindset a frat boy has, but Dale has his own unique charms.
