"Star Wars" star Oscar Isaac was on "The Tonight Show" where he talked about how he brought his "Star Wars" superfan uncle to set and director J.J. Abrams gave him a walk on role. "My Uncle came to set with all these shirts he made with everyone's names on them that said Estar Guars," said Oscar. This caught J.J.'s attention who said, "You might be a little short for a stormtrooper." It all worked out, though and according to Oscar, "They made him an extra. They put him in full makeup."
