Kilmer Replaces Arnett as K.I.T. in ‘Knight Rider’ Remake. Val Kilmer will voice the new Knight Rider car in the upcoming TV remake. K.I.T was originally to be voiced by Arrested Devlopment star Will Arnett (Gob) when producers learned that a truck commercial deal would prevent him from playing K.I.T. on TV. Kilmer, a fan of the original series, was asked to step in and become the motor mouth of the project. The Doors star says, “Will Arnett was seen on a car commercial and the producers found out that his voice was owned by that car company. They found out by accident. “So I get the call from my agent, who asked me if I wanted to be the voice of K.I.T. I remembered that show and it was fun when I was a kid, so I said, ‘Sure, should I do a tape?” My agent said, ‘No, it’s not an audition, they’re offering it to you.’ I had to be on set at 7am the next morning. EXTRAs: Kilmer recently signed on to the Werner Herzog’s crime drama ‘Bad Lieutenant’, starring Nicolas Cage and Eva Mendes.
