LOS ANGELES -- Two of the biggest TV stars from decades past spoke at length Monday during the CBS portion of the TV Critics press tour.

Robin WIlliams, who will co-star with Sarah Michelle Gellar in the sitcom, "The Crazy Ones," said it was "great to have a steady gig after so long."

David E. Kelley, who penned the pilot, said Williams would do each take as written and then was allowed to improvise in the second take. Each episode will most likely end with outtakes so people can see Williams get a little nuts.

Arsenio Hall, who is also returning to the small screen with a reboot of hissyndicated late-night talk show, said that despite the growing number of competitors, there is still a large segment of the audience who are searching for a show to call their own. But he acknowledged the rise of Jimmy Kimmel and Jimmy Fallon by saying he was at the courtroom this morning trying to get his name changed to Jimmy. The show, produced by CBS Paramount, will debut locally in September on WUCW.
