[Roberts says he would recommend video acting to any celebrity, as long as they understand it's not really acting at all:] The only similarity is they both have storyboards and they're both on film, ... Other than that, it has no semblance to acting, in that what you're doing is you're reacting to what's around you, and the music. You can't do that as an actor; you really have to focus on why you're in a scene, and you can't do that in a video because it's all such quick cuts, it's all just images.
