If I was famous, I would totally pull one of those random cameos, like just dressing up as a stormtrooper or something. And if I could pick any franchise, the Jurassic Park and Jurassic World movies would definitely be right up there.

Frankly, I wouldn't want any real screen time (no offense, Ed Sheeran), but just like a background dude doing something interesting or funny.

This singer-songwriter pulled off my dream with a cameo in the first Jurassic World. Who was it?
