The Simpsons: 15 Huge Guest Stars & Cameos You Forgot
3. Brendan Fraser
Traditionally, Homer Simpson has never been in great, good, or even average shape. He's always been an overweight man who at one point genuinely thought that he was supposed to drink eight glasses of gravy a day.
After being embarrassed while playing capture the flag with Bart and his friends however, and with the help of Rainier Wolfcastle, he worked his way into peak condition. It was at this point that he was approached by two representatives from the Powersauce energy bar brand, one of which was portrayed by Brendan Fraser.
In the prime of his career, just one year removed from the release of George of the Jungle, and just before starring in The Mummy, The Simpsons brought the star in to play Brad to convince Homer to climb the Murderhorn.
Frasier has played many different roles and different types of character throughout his career, but his voice perfectly captured the muscle bound salesman style of the Powersauce man in 'King of the Hill.'
