Well, there is a lot of homoerotic subtext, either deliberate or inadvertant in the old buddy movies. I remember Simon Pegg on Jimmy Kimmel saying that they deliberately played that subtext up in the movie as he sees a lot of subtext in the other movies. He gave as an example the end of "Lethal Weapon 2" where Danny Glover is clutching a wet Mel Gibson to his chest and murmuring "I've got you, baby".
