A carmaker conflict has caused NBC to hire Val Kilmer to replace Will Arnett as the voice of KITT on its "Knight Rider" revival.
Arnett ("Arrested Development") had already completed his part for the pic, which is slated to debut on NBC in less than two weeks. Producers Doug Liman, Dave Bartis and Dave Andron -- along with the network and studio -- were all fine with his performance.
Problem is, Arnett had a contractual conflict of interest.
For the better part of a decade, Arnett has done voice-over work for General Motors -- as the voice of GMC Trucks. NBC's new "Knight," however, is "played" by a Ford Mustang.
