16 Deleted Comic Book Movie Scenes You're Not Allowed To See
14. Pepper Was Pregnant - Captain America: Civil War
Ultimately, the reasoning the Russos gave for cutting Civil War - making Tony Stark emotionally vulnerable so he reacted to the revelation of Bucky's murder of his parents - was a good one, but there had been a different plan that changed absolutely everything.
According to one listing of the Deleted Scenes, there was some dialogue between Tony Stark and Cap that suggested Tony and pepper had broken up before the movie because he had "missed his lamaze classes". Classic Tony.
When the final film came out, the scene had been replaced with the following exchange that referenced the earlier version:
Steve Rogers: Is Pepper here? I didn't see her.Tony Stark: We are kinda... well not kinda...Steve Rogers: Pregnant?Tony Stark: No, ha, definitely not. We're taking a break. It's nobody's fault.
Why It Was Cut
It's not clear where the material was cut, or if it was actually filmed, but it absolutely would have complicated matters way too much (though it could have been wiped away as a joke, of course), so the changed line about taking a break was used instead.
