NOAH WHO?

John Leguizamo
Marking his first major drama-series gig,
John Leguizamo is joining the cast of
ER this season, TVGuide.com has learned. Details about his role could not be immediately confirmed, but sources say the actor-comedian will play a new doctor at County General in at least 12 episodes beginning in late October.
ER producers have been on the prowl all summer for a big-name actor to fill the void left by
Noah Wyle. Their first choice,
John Stamos, was forced to nix the gig after ABC went and renewed
Jake in Progress for a second season. Turns out that wasn't a joke; they really did renew it.
