No, don't worry I wasn't commenting on your name, it's mine that has the TM implications.
Yes, you're right it's an OK typo. In my experience though with names of famous people if you can't sell it to them directly or their people then you have one of two options:
a) Create a fan site and try and squeeze some revenue out of it.
b) Park it at sedo or Namedive and live off the PPC rev.
In terms of effort versus results, option b) tops my poll everytime.
