Only with Rumer Willis would these kinds of roles make news. Rumer is going to be in an episode of Army Wives over on Lifetime. She is going to play the wife of a soldier injured in Iraq. To all the other actors and actresses in the world, these kinds of roles are used as building blocks to bigger things and also as a paycheck so they can afford rent.
Now, I didn't see House Bunny so I don't know if Rumer is any good in it at all. Maybe she is. Maybe she leaves so stunned at her talent that you walk out of the movies in a daze. If so, then I admire her for doing what every other actor does and using these small bit parts to learn her craft. If, on the other hand she sucked balls in House Bunny and has no hope of ever amounting to anything other than a familial oddity, then it kind of ticks me off that she is taking these smaller roles for herself and depriving someone else of a paycheck. She doesn't need the money and if she knows she sucks, then she shouldn't let producers offer her roles simply for the publicity she will bring, while depriving someone else who is good, but doesn't have famous parents.
As for the acting gene. You know, Bruce Willis is a star, but he only has one character. One. Demi Moore. She is a little more versatile but I don't think any of us would say she is one of the best actresses of this generation. Anyway, I know lots and lots of you watch Army Wives, and Rumer's episode is supposed to air on October 12th.
