Don't know about Bruce, never saw Hudson Hawk.
Clint may have sung in "Paint your wagon", but I notice he didn't do it again.
(The Duke was supposedly a 'singing cowboy' when he was getting started in the '30's, but you'll notice THAT didn't continue.
And Blazing Saddles, History of the World, and High Anxiety were NOT musicals, they were comedies. MOVIE comedies.
As for all the ladies in those movies you mentioned, I'm not as interested in almost-naked females from movies made in the '30's. I'm sure they were pretty risque back in the day, but that was then and this is now. Gimme Megan Fox in almost nothing. She might not be the brightest bulb in the
box, but if I wanted quality, thoughtful entertainment (Which sometimes I do) I wouldn't be watching a no-brainer action flick full of action, violence, and some nudity and/or adult situations. I LIKE no-brainer action flicks like that sometimes. Quite a few sometimes, because it lets me forget about other things I have to worry about the rest of the time. There are times I want to be entertained without having to figure out a plot, storyline, innuendos, sub-plots, and the like. Those are the times I want action, violence, fistfights, swordfights, gunfights, explosions, Chuck Norris, ass whoopins, car chases, Bruce Willis, robots and/or cyborgs, stunning special effects, hot naked chicks, computer graphics, shooting, hot naked chicks, Arnold, Naval bombardment of anything filled with the enemy by the biggest freakin' battleships we ever had, hot naked chicks, .50 BMG sniper engagements of insurgents at obscenely long ranges, Tom Selleck using a .45-120 for ultra-long range shooting of boneheads who deserved it, and more hot naked chicks.
