3. Emily Blunt "Unofficially" Linked To Captain Marvel
Despite the revelation that Avengers: Age Of Ultron will introduce so-far unnamed supporting characters played by Julie Delpy and Linda Cardellini, it seems unlikely that either will be unveiled as Captain Marvel in the ensemble sequel. After all, Disney surely wouldn't allow their names to leak at all if that was the case. Instead, it looks like another actress will take on the plum role; Emily Blunt, who has already been offered two roles in the MCU and turned both down. Rumours persist that Disney and Marvel still want her, and she's aware of the fan calls to see her join as Carol Danvers:
Oh! No ones offered me that officially, so its very unofficial. I think its fan-casting, which is always very nice. But nothing official has been offered, for sure. If I get it, thank Meryl for it!
Chances: 6/10 It might be three times a charm, but there are few fans who would suggest that Blunt looks right for the part. Stranger things have happened though.
