Yep, Sly isn't a tall man. If you ever saw pictures of him with Bridget Nielsen you can see it. If you think about it everybody in the Rocky movies, Carl weathers, Mr. T., Micky, was a little on the short side so he didn't seem too short by comparison. Then in Rocky 4 when they brought our Dolph Lundgren he looked like a giant, but he was only 6'5" or so. But next to Sly he looked 8 feet tall.
John Wayne was one of the tallest actors in Hollywood though at the time he was working. He was 6'4". Not saying they didn't put him on a small horse to make him look even bigger though. Course it might have been just so they could keep him in the frame with the other actors.
