A brief roundup of a few TV casting reports:

• Will Arnett has signed on to star in the untitled CBS sitcom created by Greg Garcia (Raising Hope).  Not a great sign for Arnett’s current obligation, Up All Night.
• Steve Zahn will star in Influence, the latest drama from Kyle Killen (Awake)
• Rachel Lefevre is now the female lead in the CBS series adaptation of Stephen King‘s Under the Dome.

Ron Weasley is heading to the small screen.  Rupert Grint has been set to lead the CBS pilot Super Clyde, which centers on a young man who decides to become a superhero.  Grint will play Clyde, a fast-food worker and avid comic book reader who considers himself borderline agoraphobic with mild to severe anxiety issues.  Clyde wishes he were a superhero himself, and when he inherits a $100,000 a month inheritence from his deceased eccentric uncle, “he decides that the cash will be his secret super power and will use it only for good and reward the good-hearted.”  So it’s like a My Name Is Earl reboot with a dash of Batman thrown in for good measure.  Hit the jump for more.
