Avengers: Age Of Ultron - 15 Theories That Were Utter Bull
11. Captain Marvel Would Appear
The Theory: With the character confirmed for Phase 3, Carol Danvers would make a surprising early cameo of some description.
The Supposed Evidence: When Julie Delpy and Linda Cardinelli were unwittingly leaked as being cast members, the rumour mill spun into action, suggesting that either of them would be playing Danvers.
The Reality: An accidental red herring. There's no Captain Marvel (which isn't all that shocking when you think of the timeline of releases in Phase 3), Delpy played Black Widow's sinister mentor Madame B, and Cardinelli plays Laura Barton - wife of Dead Meat Hawkeye.
Would It Have Been Better? Introducing Captain Marvel at this stage could have meant she could pop up in other Marvel films until her own stand-alone, which might not have been the worst thing for hype building.
But let's be honest, the film was already busy enough without more characters.
