There might be tons of movies about a sexy female alien looking for a horny earthling to breed with, but there's only one Species (1995). The iconic sci-fi thriller, which is even rumored to have led to the creation of the chupacabra myth, kicks off with the US Government getting a message from aliens. It's got the blueprints for a bunch of super helpful, advanced technology, as well as a DNA sample the aliens want humans to splice with theirs. The government does just that, creating Sil (Natasha Henstridge), a fast-growing alien-human hybrid. What imbeciles! Eventually, she'll escape captivity and set out to get knocked up by whatever human she can, which leads the government to create a team to track her down including badass soldier Press Lennox (Michael Madsen), anthropologist Dr. Stephen Arden (Alfred Molina), molecular biologist Dr. Laura Baker (Marg Helgenberger), and telepathic dude Dan Smithson (Forest Whitaker). Suddenly, it's a game of cat and mouse between the gang and the alien girl letting all sorts of dudes play with her kitty. The flick that made Henstridge a star and launched its own franchise featuring a bunch of sequels, the film might be best known for Natasha's knockers, but there's some dudity too! A very much in his prime Michael Madsen flashes some booty and upper body when he crawls out of a hotel room bed and pulls up his pants on his way to answer the door. We get a good look at his ass and lower back dimples, then we see his chest when he answers the door. That'll have you dinging your dong! As a sleazy but sexy dude Sil hooks up with, Anthony Guidera is steamy, wet and hot when he gets out of the shower and dries off while the alien/woman watches him. We get to see his washboard abs and some side butt when pulls on his pants. His body is out of this world! If you're into men, you won't find two hotter specimens than those two in Species!
