Robin Williams might just have been the greatest performer of our generation. A talented stand-up comedian, writer and actor, he was also an all-round nice guy who was loved by millions. Since he died last year, there’s been a gap, a noticeable lack in laughs coming from Hollywood. So it’s nice to see someone reminding us of his great skills. And that guy is Jamie Costa. His impersonations of Williams are out of this world. His voice is spot-on, but he also has the facial expressions down to a tee too. He even looks a bit like him (with hairy chest and everything!).
