I was always drawn to Scotty.
Was it because of the increased gravitational effect of his enlarged mass?
I was thinking about this the other day, that TOS mains sometimes didn't have much of a career after the show. Shatner did, of course, & Takei. Nimoy & Koenig, kind of (the latter taking some years to really ramp up again). Kelley, Doohan & Nichols...far less so. I don't think it was typecasting but almost an inability of the industry to see them in anything BUT that role.
