Apatow comments in Rolling Stone on Williams’s uniqueness as a performer:
You can’t look at any modern comic and say, ‘That’s the descendant of Robin Williams,’ because it’s not possible to be a Robin Williams rip-off. He was doing something so unique that no one could even attempt their version of it. He raised the bar for what it’s possible to do, and made an enormous amount of us want to be comedians. He looked like he was having so much fun.
