And Mark Hamil is not as heavy as you make him out to be, I just saw him 3 weeks ago at the BAFTA LA Behind closed doors Q&A and yeah hes a bit bigger than his ROTJ days, but he is no where in the same league weight or size wise as Shatner or other actors who have gotten bigger as they got older. and certainly nothing that he couldnt rid himself of when prepping for a role.
