Even in an era long before Hollywood became franchise obsessed, its success ensured a sequel would be made. But while many sequels in the realm of big studio franchises tend to play it safe, this one did not. 1970’s Beneath the Planet of the Apes is a bizarre, head-turning follow-up that goes (pardon the pun) fully bananas, quite literally blowing up the franchise in the process. Though not necessarily beloved in its day, 55 years later, it’s hard not to respect just how crazy it really is. Through a modern lens, it’s staggering to consider that this was a theatrically released, studio sequel to a giant, mainstream hit.
