I know, I was shocked, too. The tall, icy-blonde stunner Gem in Tron is NOT supermodel Jessica Stam. But look at those faces! The same, the same! Gem is in fact played by model/actress Beau Garrett, who previously appeared in Entourage, House and Fantastic Four: Rise of the Silver Surfer. Meanwhile, Stam stomps the runway for everyone from Victoria’s Secret to Dior and appears in ad campaigns for Aldo, Chanel and Bulgari. Craziest part is, out of hair and makeup the two look nothing alike. That’s movie magic for you.
