Re: Comparing actors' portrayals of the same role (possible spoilers)
Cumberbatch is far better actor than Montalban. His Khan was far more nuanced, especially when compared to TWOK Khan. But there is something about the way Montalban chews the scenery.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
