I would never do a commercial for something that is embarrassing and I think that people maybe have a different perspective on what is embarrassing or not. Some people think doing a Revlon hair commercial is really cool. To me that's embarrassing but World of Warcraft - not embarrassing very cool.
If you do too much acting in a lead part in a feature film where you're 40 ft. high, it's rather unattractive. You can see the acting. And it's actually the right thing to do to bring as much of yourself, I believe, to the part as you possibly can - to minimize the amount of theatrical stuff that you need to do.
