4. James Cameron (Ubisoft, E3 2009)
Fifteen minutes. What is fifteen minutes to you? You could do a whole lot in that amount of time. As a game publisher at E3, that's enough time to show off several high-profile games, talk about your plans for next-gen consoles, or do something, you know, exciting. That wasn't how Ubisoft wanted to spend their time at E3 2009. Instead, they decided to bring movie director James Cameron to the stage and promote the movie tie-in Avatar game. While most celebrity appearances are there and gone in a matter of minutes, Cameron went on a filibuster as he rambled on for an excruciating quarter hour about how awesome Avatar: The Game would be.
Don't get us wrong, we love getting a behind-the-scenes perspective on how good games (and movies) are created, but in hindsight, the game wasn't that good and he didn't show any footage from the film, so the fact that we had to sit through that presentation sucked. He tried really hard to pump up the future flop as much as he could, but alas, now his efforts can only be seen as a futile attempt to get a famous face to push a poopy product.
