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.

Thanks LW. Good info and it makes sense, now.
Coogan’s Bluff was a good early Eastwood film.
