More casting news after the jump.

You could say that most people's interest in a new comedy from Friends' star Matthew Perry called Mr. Sunshine, would be pretty high. He's a popular actor. Friends was a popular show. People reacted favorably to Courteney Cox's new comedy Cougar Town... You see where I'm going here.

Well, the interest meter just moved up considerably because West Wing Emmy-winner Allison Janney will co-star with Matthew in Mr. Sunshine. Mr. Sunshine is an ABC pilot they'll be filming, and it's about a guy who reaches his 40th birthday and wonders if he can continue just getting by on his charm and nonchalant style.

Mr. Sunshine is set in San Diego, where Perry's character manages an aging stadium. Janney is playing Crystal Cohen, the lady in charge of the place. That's right; she's Matthew's boss.
