I can recall many people, especially actors and actresses, who damaged their careers by trying to destroy their perceived public image and try something different just for the sake of saying you changed and didn't want to be streotyped a certain way. Think of the cast members of Gilligan's Island and The Brady Bunch. Many members wanted to 'distance' themelves from their image and denounced anything to do with it trying to explore different things. But in the end they found they were wanted and loved best for the image they already had! Many of them like Florence Henderson and Susan Oleson have realized this and have gone ahead and capitalized on it, laughing all the way to the bank. Compare that to Tina Louise, who didn't want to be thought of as Ginger, so now she really isn't thought of at all.
Think of Donny Osmond trying to destroy his image by acting like a bad boy, or MC Hammer going 'gangsta'- these things didn't fly and their careers were damaged. How about Debbie Gibson dressing more mature and changing her musical style as not to be thought of as a teen pop star? That was not what her fans wanted, and it destroyed her recording career. Who cares what the fans want? Have that attitude and you will find yourself back on Broadway instead of Hollywood. I could go on if I sat and thought about it. It's like a writer trying to write about something he doesn't know, they always say stick to what you know.
Everyone should do they do best, and not try to be something different just to prove something. Why? You're good, you rock, and your fans love you. If it ain't broke don't fix it. You might just really 'fix' it in the process and the repairs could be costly!
