In 2007, Katz joked to "Blast Magazine" entertainment editor Bessie King about the success of his Comedy Central show and the recent release of the full series on DVD. "I’m so proud of that work and I’m a compulsive name dropper, when I did a movie with Ice Cube over the summer I said...I hope my best work is not behind me but if it is, I’m glad it's "Dr. Katz"," he said. In 2007, he released a stand-up album titled "Caffeinated". In 2009, he can be seen (or heard) as Freezy, the Burl Ives-inspired animated snowman star of "Turbocharge: The Unauthorized Story of the Cars", a comedy biopic about The Cars, which Katz narrates throughout.
