I think they are about the same height. And yes first blood is still awesome and relevant today just as when it came out. Same with Die Hard and Lethal Weapon and Predator.
Last night my son had a friend sleep over. Both boys are 9 years old. At one point I asked his friend about his favorite movies to see what he'd say and of course he mentioned SW and Marvel. Then he said he also likes the one with the alien and the world's greatest bodybuilder. I actually blanked on what he was talking about and assumed he meant the Rock was all "uh Jumanji?"
And he he said no the one where the alien kills all the body builders and I was all holy crap you mean Predator, lol. And he said "yeah that's my favorite old movie." Who the hell calls it the old movie with the alien and the bodybuilder, lol. It was like something MCU Spider-Man would say.
It's crazy that we live in a world where kids don't know Arnold by name. My kids sure as heck do so I just assumed that all dads were raising their kids right, lol.
