It looks like Captain Marvel included two massive comic-book cameos â€“ with one featuring a character weâ€™ve seen onscreen before.
But letâ€™s start with the clearest cameo, which was almost certainly deliberate, if a little subtle.
Monica Rambeau (Akira Akbar) is the daughter of Air Force pilot Maria Rambeau (Lashana Lynch), who is the best friend of pilot Carol Danvers (Brie Larson) in Captain Marvel.
Comic-book fans will recognise that name. As an adult, Monica Rambeau is a major black female superhero whoâ€™s also gone by the secret identities of Photon, Spectrum and â€“ significantly â€“ another version of Captain Marvel.
So Marvel were basically stealth setting up a potential future reboot, which weâ€™re sure Brie Larson will be happy about.Â But with Captain Marvel going great guns at the global box office, we might have to wait a while before Larson hangs up her super-suit.
But thereâ€™s another potential cameo, even if this is a little bit more tenuous. Still, itâ€™s an interesting fan theory, which appeared over at Reddit. According to chrisHANDmade, the moment where Carol Danvers sees a shooting star with Monica Rambeau, theyâ€™re actually looking at Peter Quill being taken from earth. Yep, seriously.
The maths adds up, we know the main events of Captain Marvel happen in 1995, and in the credits, the two Monicas are listed as â€˜Monica Rambeau (11 years old)â€™ and â€˜Monica Rambeau (4 years old).â€™ Thatâ€™s a seven year gap, and 1995 minus 7 is 1988, which is the year Peter was taken.
Look, we said it was tenuous, but itâ€™s a very fun easter egg if itâ€™s revealed later down the line (possibly after Endgame).
