Noah Wyle: Fearless 'Librarian'

Noah Wyle is back in a big way, reprising his role as Dr. John Carter for the final four episodes of "ER" -- and now saving the world with a third installment of his hit 'Librarian' series. Read on to find out which classic foe he faces! "I've had more fun making these movies than anything else I've done in my career," Noah tells ET about his 'Librarian' adventures. 'The Librarian: Curse of the Judas Chalice' debuts Sunday night at 8 p.m. on TNT. This time, Noah's overworked Flynn Carsen heads to New Orleans for a little R&R, instead finding himself tasked with rescuing a professor (Bruce Davison) and fending off bad guys intent on using the silver chalice (given to Judas for betraying Jesus) to resurrect Prince Vlad Dracul himself and raise an army of vampires.
