King Kong vs. Godzilla (1963). FilmPublicityArchive/United Archives/Hulton Archives via Getty Images It’s east versus west, giant reptile versus mega-mammal, the “Big G” versus the “Eighth Wonder of the World.” Godzilla vs. Kong—a new slugfest from Legendary Pictures—is set to be released in theaters and on HBO Max on March 31, 2021. But it won't be the first time these two iconic movie monsters have faced off. They met once before in 1962’s King Kong vs. Godzilla—a crossover battle for the ages that also featured a rampaging octopus and a future Bond Girl. Not to mention the craziest tree-related violence you’ll ever see outside an M. Night Shyamalan flick.
