McCloud was just a spin off of an earlier Universal movie starring Clint Eastwood titled Coogan's Bluff.

Universal had the writer-producer Glen Larson adapt the movie Coogan's Bluff into the series McCloud.

Larson did that with a number of Universal movies, for whom he worked under contract.

FWIW.
