​The audience for CineEurope this last Wednesday were treated to an exclusive teaser for Captain Marvel and Avengers 4 from Marvel Studios, and details regarding the releases show some major shake-ups from Earth's mightiest heroes come Summer 2019.

The events at CineEurope call for fans to lock up their phones, so not much has leaked in regards to what the attendees have seen, but according to ​The Hollywood Reporter, Marvel Studios President Kevin Feige "served up some exclusive glimpses of the untitled fourth Avengers film," as well as a Captain Marvel trailer.

Someone during the feature stated "Captain Marvel is about to take the lead in the entire Marvel Cinematic Universe," as leaks on Twitter begin to report, adding to the rumors Brie Larson's portrayal as Captain Marvel will replace the hole left by Robert Downey Jr. and Chris Evans' departures. ​CBR also reported an attendee leaked that Captain Marvel is gearing up to be "the new face and leader of the Marvel Cinematic Universe.”

CineEurope attendees were also shown previews from other Disney properties such as Ant Man and The WaspToy Story 4, Mary Poppins Returns, Aladdin, The Lion King, Ralph Breaks the Internet, and Tim Burton's Dumbo.

Captain Marvel premieres on March 8th, 2019, with Avengers 4 following two months later on May 9th, 2019.
