Mark Amato

Quickly making the segue to full-time writer, Mark has written in almost all fields of television including sketch, half-hour, Sci-Fi, animation and movie-of-the-week.

Mark has written television abroad as well, working in Toronto, Montreal and the U.K. Beyond earning shekels for the written word, Mark consistently finds new ways to tickle audiences like co-creating the hilarious showbiz skewering website (which Entertainment Weekly dubbed, “wickedly mischievous”), wrote and starred as Jerry Lewis in “The Last Telethon” at the Comedy Central Theater last December, as well as winning the dubious title of “Best Christopher Walken impression” after his YouTube video “Christopher Walken as a Nursery School Teacher” went viral.
