OK, so this is TV rather than film, and American TV at that. But it's also Knight Rider, the TV movie that may prove to be the pilot for a new series, and anything with Val Kilmer in is news, right? You betcha. So it is that Val Kilmer is replacing Will Arnett as the voice of K.I.T.T. in the new Knight Rider movie, which will, its makers hope, kick off a whole new man-and-his-talking-car series.
Arnett, who you should know from Arrested Development (seriously, go watch it already) but who you're more likely to know from Blades of Glory (wherein he played the sneery ice dancer) or Hot Rod (wherein he played the sneery love rival...there's a theme here). He's also done voice work in Ratatouille (he was scary chef Horst) and, fact fans, was the trailer announcer on Edgar Wright's Don't trailer in Grindhouse. But for years he's voiced adverts for American car manufacturer General Motors, who were less than thrilled when they heard he was doing a voice on the (very) Ford-sponsored Knight Rider reboot. So Arnett is out and Kilmer is in for the show, which is due to air in less than two weeks.
Either one of them would have been interesting for this, but given that the only requirement for K.I.T.T. is that he sound smarter than his driver (in this case played by Justin Bruening, formerly of 'All My Children') either Arnett or Kilmer should be able to do the job.
