The actor whose uncanny Robin Williams impersonations went viral is back again with a new series of celebrity impressions.

Jamie Costa uploaded a video to YouTube called, “Gandalf and the Fellowship of Celebrities.” He perfectly mirrors Gandalf from “Lord of the Rings” when he asks, “Who else will help me go through middle earth and destroy the ring?”
