Stallone's stuntwork is incredible in Rambo III
Most of the scenes you see Stallone doing in this movie would never be done today by a Hollywood actor. I'm especially amazed at the scene when the Russians attack the Afghan camp during the sheep game. Those choppers are flying awfully close to the ground. I read somewhere that Stallone was nearly decapitated during one of those shots when he was on horseback. That's how low they were flying.
Another impressive shot is the slow motion one of Sly bending down to grab the sheep from atop the horse during the game. Yes his strength is impressive but even more impressive is how dangerous this stunt really is and it's all him. Going full speed and reaching that low from that high up could have been disasterous if he had accidently fell off.
Everything about this movie blows me away. They can have their green screen CGI comic book movies. I'll take the legendary Rambo series which each movie was shot in harsh, spirit breaking conditions and where the star actor did more of the actual stunts than these new actors could ever dream about doing.
