I thought the Magnificent Seven might have been the movie I was looking for. But that doesn’t seem to be the case. I remember a movie with a stagecoach with a lot of help to protect the big gold shipment. Don’t remember much else. Could it have been a sequel to The 7 Series? I can’t find it.
“The War Wagon” (1967)?
Gold of the Seven Saints?
No stagecoach though.
“The 5-Man Army” (1969)?
