The Terminator (1984)

One of the most iconic science fiction movies of all time, James Cameron's The Terminator (1984) created a legendary franchise that's still making money, turned Arnie into a superstar, and made "Cyberdyne" the go-to reference for why we shouldn't mess around with AI. In the film, Sarah Connor (Linda Hamilton) is an unremarkable waitress living in 1980's LA. But it ends up, in 2029 her son John Connor will lead a revolution against the machines: artificial intelligence that has nuked the globe and tried to exterminate humanity. They would've won if John didn't lead the resistance, so the desperate machines come up with a plan B. Ironically, a Plan B pill would've been more effective than what they come up with, but whatever. After figuring out time travel, the desperate machines send back a "Terminator" cyborg assassin (Arnold Schwarzenegger) to kill her before she can pop out the kid that causes them so much trouble in the future. To counter that move, the humans send back their best soldier, Kyle Reese (Michael Biehn) to use his knowledge of battling bots to protect Sarah. It's man versus machine in the fight to protect Sarah Connor! Some will claim this one's more slasher than sci-fi, and others will claim the sequel's the better piece of cinema, but few could deny that the first shot of everyone's favorite Austrian bodybuilder in the buff! And we mean buff! In the franchise's lore, you can’t travel through time without losing your clothing, which is why we see both Arnold and Biehn in their birthday suits.  First Arnold drops onto Earth in a blaze of bright light and is crouching naked in an alley.  As he stands, his body builder booty is blatantly displayed.  He begins walking away and his firm muscular back and tight buns appear otherworldly.  But wait, there’s more. He approaches a group of young toughs (including a then unknown Bill Paxton), and despite some shadows, the outline of his powerful passion pendulum can be seen swaying back and forth. Bet you'd like to pump that thing up! Biehn comes to Earth the same way as Arnold, and even though he keeps his package under wraps, there is a quick shot of him running naked down the street. Bet that had the ladies flicking the Biehn! If the Terminator movies keep bringing the cock and crack like that, We’ll be back!
