That must really suck (being Tom Thumb) but on the upside he could get a lot of money from acting if he's good. People with Dwafism are always saught after so I see no reason why he can't be a movie star.

I know that there are actors with dwarfism who want to known for casting as humans rather than dwarves, Umpaloompas etc. and they set up their own theatre company. However I can't remember the name. If it comes to me I'll post it.
