9. They Made A Batman Film In The Comics
When Superman discovered Hollywood was making a movie of his adventures with Batman, the Man of Steel convinced him to check out the set. From a distance, they watched the actor, Jason Wish, who plays James Bond in the DC Universe, perform a monologue as the Caped Crusader.
In the scene, he explains to Superman how he was inspired to take on the name "Batman" after his sister saved him from his abusive mother with a baseball bat.
That's right. Despite the fact Gotham's protector clearly wears a costume modelled on a flying bat, the studio thought he was inspired by sport equipment!
Superman found this scene so hysterical, he had to do everything in his power not to burst out laughing.
Batman rarely loses his cool over trivial matters but he was so enraged by this scene, he said it was "crap" and "ridiculous". He even asked Superman to x-ray the negatives, destroying everything the studio filmed so far.
The pair's morbid curiosity got the better of them, though, and they ended up going to the film's premiere in their civilian identities.
