If the charecter is older than the actor should be too. Sean connery did these types of movies at a much older age than harrison is now, ncluding one of the indian jones movies. Silvestre stalone is still one of the most physically fit men in the world and he's in his 60's. He is still makeing action movies and i think he should be able to i love the new rocky movie and it's about this very subject. I didn't see the new rambo but i only liked the first one so i had no interest in the fourth. Last but not least "unforgiven" starring clint eastwood won best picture in the early nineties, it is one of the best westerns ever and clint is nothing short of badass!!!
