Christopher Lloyd – Klingon Kruge

Before he cemented his iconic status as arguably the most outstanding mad scientist in cinema history, Christopher Lloyd had a role in 1984’s “Star Trek III: The Search for Spock.” He played Kruge, a Klingon character that left him looking unrecognizable in his makeup and prosthetics.

So by the time he played Dr. Emmett “Doc” Brown in “Back to the Future,” nothing but the start and end credit of “Star Trek III” were evidence of his appearance in the film. Lloyd had previously made an impression with a role in “One Flew Over the Cuckoo’s Nest.” In 2021 he appeared in “Next Stop, Christmas.”
