The Simpsons: 15 Huge Guest Stars & Cameos You Forgot
2. Jeff Goldblum
The second Jurassic Park star on this list, Jeff Goldblum has an incredibly recognisable voice that you would know just about anywhere, however his role in The Simpsons was so small, and such a long time ago, that it is easily forgotten.
In 'A Fish Called Selma', Troy McClure's romantic involvement with Marge's sister saw a brief revival of his career, which brought his long time agent, MacArthur Parker, back to him. Though he hadn't spoken to his client in years, or got him work in 12 years, he was back on the scene as soon as the rumours about McClure's aquatic sex life were in the past.
Voiced by Goldblum, Parker managed to get Troy the lead role in the Planet of the Apes Broadway show, convinced him to marry Selma, and in a bid to land him the role as the sidekick in the new McBain movie, tried to get them to have a child.
It's a shame the character didn't feature more in the show, as he was hilarious, and criminally underrated as far as one time Simpsons characters go.
