Greg Louganis, who won four gold medals in Olympic diving, is still in great shape these days, thanks in part to his workouts in spin class at Cycle House in Santa Monica. On one occasion, the casting director for "Entourage" was in the same class and thought it would be a great idea to include Louganis in the movie. This cameo is among about two dozen from notable athletes, including Russell Westbrook, Tom Brady, Ronda Rousey, Rob Gronkowski, Mariano Rivera, Baron Davis and Mike Tyson.
Even some athletes who weren't in the movie, such as Terrell Suggs, Rudy Gay and Frank Kaminsky, made it a point to attend the premiere at the Fox Regency Westwood Theater. We caught up with them and show creator Doug Ellin during the pre-screening festivities:
