The original Planet of the Apes is an all-time classic, but the beloved movie wasn't the first crack at bringing Pierre Boulle's work to the big screen. Twilight Zone creator Rod Serling wrote an early draft for the screenplay, featuring a ton of moments that never made it into the final film. And now, his story is being used as the basis for a new comic.

There are a lot of amazing new movies coming in 2018, but there's also a long list of classic, iconic films that will be celebrating significant anniversaries this year. Here are the biggest science fiction, fantasy, and genre movie milestones happening in 2018. (You should probably be prepared to feel old.)

There's no confusing Planet of the Apes: Last Frontier with a Telltale-style adventure game. There is no exploration, no dialogue trees or puzzles to solve. It's a three-hour movie peppered with simple A or B choices that influence how events play out. It's about as basic as interactive fiction gets.

In Tim Burtons' B-movie spoof Mars Attacks!, aliens invade Earth after a series of made-up cultural misunderstandings. However, what if they had waited a thousand years to make First Contact? Well, you'd probably get a decapitated Cornelius.

They have teamed up with the cast of Star Trek. They have fought Aliens' xenomorphs. And now, the Green Lantern Corps is heading to the Planet of the Apes for even more crossover shenanigans.
