A lot of times, when you get big name people in voice acting, they just kinda do their talking voice and call it a day. And I was honestly expecting more of that for his Allen, and I was worried for when we got to more Allen centered stories.
But I actually liked his performance. He seems to have a distinct voice for the character. And we didn’t have any occurrences of his infamous chuckle in it either.
It makes sense I guess, he’s an executive producer on this, and I think he really wanted this project to happen.
He’s actually a more capable actor than he gets credit for because, like Adam Sandler, he mostly does movies with his friends and just plays mostly his self. In things that require more range and nuance he has always nailed it(other than green hornet)
