So THAT'S why Batman and Superman are at war.
If, like us, Batman v Superman: Dawn of Justice left you dazed and confused about, well, pretty much everything, talkshow host Conan O'Brien has shed light on one conundrum.
What to Read Next
Years ago, Batman (Ben Affleck) and Martha Kent (Diane Lane) slept together! Sort of.
Conan's theory – presented to the assembled Batman v Superman cast including Henry Cavill, Amy Adams, Jesse Eisenberg, Gal Gadot, Laurence Fishburne, Holly Hunter and Zack Snyder – stems from a photo of Affleck and Lane in bed together.
Joke's on us, though - the pic is obviously a still from the 2006 drama Hollywoodland, where Affleck's George Reeves and Lane's Toni Mannix got it on. Classic Conan.
But after two hours of hating and plotting to kill one another in Dawn of Justice, it turns out there's one very common trait that Batman and Superman share...
Both their mothers are called Martha. It's this reason alone that Bruce Wayne spares Clark Kent's life at all.
Batman v Superman : Dawn of Justice is in cinemas now. Watch a trailer below:
