He was in all kinds of movies, those bad 70s John Wayne flicks that were ripoffs of big movies (either Branagan, which was a rip off of Dirty Harry or McQ a rip off of Bullitt ).
I read in an article that Roger Mosley didn’t even want to do a tv series…his agent told him to take the job recording the first episode (a pilot, not to be confused with the HELICOPTER PILOT he played, and was one in real life!)
Anyhoo, the agent’s reasoning was that it was a Tom Selleck tv series and his previous 4 attempts weren’t successful, so the agent figured it would be a sweet paycheck (correct) but for a brief vacation in Hawaii.
Went for 8 or 10 years lol.
