Eddie Kaye Thomas cast in 'America'

Misha Collins becomes 'Supernatural' regular

Eddie Kaye Thomas has joined HBO's upcoming comedy series "How to Make It in America" as a regular.

Additionally, Misha Collins has been upped to a regular on the CW drama "Supernatural," and Stephen Dunham has been added to TBS' comedy "The Bill Engvall Show."

Thomas guest-starred on the pilot for "How to Make It," which revolves around Ben (Bryan Greenberg) and his friend Cam (Victor Rasuk), enterprising twentysomethings who hustle their way through New York determined to achieve the American dream.

Thomas plays a guy who went to high school with Ben. He now runs a hedge fund and is extremely rich but wants to be cool -- at any price.

Thomas, who starred on Fox's " 'Til Death" and voices a character on "American Dad!" is repped by Gersh and Untitled.

Collins had recurred on 12 episodes of "Supernatural," morphing between otherworldly angel Castiel and hapless family man Jimmy Novak. He is repped by SMS and Framework.

On "Bill Engvall," Dunham will play Engvall's brother Kenny, a likable ne'er-do-well who gets by on his charm. Domain-repped Dunham ("What I Like About You") joins as a recurring this season with an option to become a series regular.
