Brian Thompson(I)

Has a long history with Star Trek, having appeared on three television series and one film, as two Klingons, a Dosi, a Jem'Hadar and a Romulan.

If you're very physical in stature, you're gonna get hired for action movies. The star's always going to be chasing someone so they need an equal adversary. I'm never going to play a nebbish geek. Whereas Linda Hamilton, as Sarah Connor, she was an equal adversary too, she had balls.
