Nick Nolte and 'Spock's Brain' (Star Trek)
Does anyone know if Nick Nolte is in this episode? His first credit on IMDB is a Walt Disney production from 1969, and it listed him as 'uncredited', while 'Spock's Brain' was produced in 1968, just a year earlier, or perhaps only several months earlier, depending upon production times. This makes it entirely possible, period wise.
To see who I'm talking about, check the primitive cave men on the ice planet. We get a clear shot of four of them facing the camera at one point, and I believe it is a bearded Nick Nolte on the far left.
Does anyone agree with this?
