Billy Crystal, consummate, old-school stand-up comedian. In an interview once, Gregory Hines commented on Crystal's expertise saying, "He's Billy Crystal, he can do 20 minutes on this...", picking up a catsup bottle from the condiments rack.
Absolutely love how hyped Billy is at the end of it, you can see he's juiced, and you can tell the exact moment he "loses himself" in the performance. When he says "and I'm gonna be the first man to win the heavyweight title for the first time, NOBODYS EVER DONE ANYTHING LIKE THAT!", from that point through the end, Billy got to be Ali for a minute
This was so good I watched it twice. Two of my favorite people in it together. One at the beginning of their career, and the other at the end. Beautiful symmetry.
