The lead role in an NBC comedy pilot has gone to an actor best known for his regular role on Showtime’s "Weeds," TVLine.com reports.

Justin Kirk joins “Animal Kingdom,” where he will play Dr. George Coleman, a misanthropic veterinarian along the lines of Hugh Laurie’s character on Fox’s "House." The guys likes the animals, but generally loathes the owners of the pets.

The show will be filmed from a script by Brian Gatewood and Alex Tanaka. Anthony and Joe Russo are directing the pilot.

Kirk reportedly continues to negotiate with Showtime about his role in “Weeds,” and word is he could continue to work on the show through its upcoming eighth season, which would wrap before “Animal Kingdom,” if it gets picked up to series, would get up to speed.
