Seeing double: Near-identical films that came out at the same time

They are showdowns that didn't need to happen — rival studios staring each other down, refusing to blink.

In 1998, Earth-snuffing asteroids got blown up in the nick of time by nuclear warheads, not once but twice, in Armageddon and Deep Impact. That same year, animated insects skittered onto movie screens in Antz and A Bug's Life — and just a year earlier, dueling lava flows erupted in Dante's Peak and Volcano.

And in 2013, Jesse Eisenberg starred in The Double, and Jake Gyllenhaal in Enemy, each as a man tormented by his doppelganger (and wouldn't you know that Enemy was based on a novel called...wait for it... The Double.)

Hollywood is not a big town. Everyone knows what everyone else is doing, and movies that cost millions of dollars require many people and many months of development. Yet they still ended up in '87/'88 with four body-switching comedies: George Burns turned 18 Again!; fathers Judge Reinhold and Dudley Moore each switched places with sons in Vice Versa and Like Father Like Son, respectively; and in Big, an amusement park wish turned a little boy into Tom Hanks.

This is not, from a business standpoint, smart. One film will inevitably come out on top (only Big attracted substantial crowds in that mid-'80s body-switching smackdown) and arguably nobody emerges unscathed.

And yet....

Here's a (far-from-definitive) list of 50 conceptual twins that went head-to-head for no discernible reason.
