According to The Arnold Fans, Arnold Schwarzenegger has a cameo appearance in "Helldorado", featuring The Rock. Their source says "Yes, Arnold did make a cameo appearance in Helldorado, directed by Peter Berg and starring The Rock. Arnold had lunch with the Rock in the catering tent with the cast and crew, where Arnold and Rock took photographs with various people. From there he headed to wardrobe where they fitted him with a very cool outfit. You’ll have to see the film to find out what Arnold is wearing! The bit was shot on 1/15 at the Ivar Club in Hollywood and took about 20 minutes." Another rumour, suggesting The Rock made a cameo in Arnold’s film "Terminator 3" has proved untrue. Thanks to ‘ULF’
