Here at Mr. Man, we've seen our fair share of post-apocalyptic movies. There's something about anarchy, lethal epidemics, rampant zombies, and killer robots that seems to makemen strip off all their clothing. Maybe it's sheer abandonment of society's expectations, ormaybe you just don't care about your clothes when you could die at any moment. All we know? We wouldn't mind the end of the world if it meant foraging for food and seeking shelter with these sexy men.

You know the drill: Boy wakes up alone (and naked). Boy stumbles around the desolate, now-decrepit hostipal (naked). He searches for fellow human life, eventually realizing the end of the worldas weknow it has finally come.An interesting animal activist/ape approach is used in this post-apocalyptic movie, and Cillian Murphy does not disappoint in the penis department. Watch for his wake up from a lengthy coma, when he hops out of his hospital bed completely nude.

2. Keanu Reeves in The MatrixReloaded

And when zombies aren't the end of the world, you can look to robots, which will indubitably rule over all of humanity one day. We'll give it to Keanu Reeves in this flick, thoughhe may play an office droid, but he looks damn good doing it.

3. Bruce Willis in Twelve Monkeys

A deadly epidemic and time travel weave a pre-apolcalyptic tale about a futuristic man's efforts to save a doomed population. Bruce Willis overshoots his leap backward in time, though, and he struggles to fulfill his mission in a world that thinks he's totally bonkers. At one point, he gives his fans a full-frontal shot of his naked bod in a war trench. Bruce Willis's peen? War trenches from the past?We knowit'll all make sense later.

4. Viggo Mortensen in The Road

Last but not least isthe cinematic rendition of Cormac McCarthy's The Road, in which the father is played by none other than Viggo Mortensen. In this case, your personal road leads to Viggo's booty and balls when he hops in a waterfall for end-of-the-worldbathtime. Hey, the end of the world doesn't mean the end of hygiene.
