G) Will Smith: himself, the Fresh Prince of Bel Air
H) Robert Patrick (other than the T-1000): that makes no sense
K) Robin Williams: himself, he is a standup comedian after all
Most famous for their overall work I'd say
I already explained the T-1000 omission. In that instance, I'm asking for the second most popular choice, since the first choice would be obvious for everyone. And your Robin Williams and Will Smith choices are not movie roles.
