A new casting call for the fourth Avengers movie may just tease the arrival of Wiccan and Speed in the Marvel Cinematic Universe.

A casting call from Auditions Free has revealed Marvel Studios is looking for a pair of identical twins aged around two years of age. The shoot would only be for a couple of days so their screen time would be minimal, but it's easy to speculate that Scarlet Witch and Vision's relationship is moving full steam ahead - following Marvel Comics.

Previous set photos have shown a romantic kiss being shared between the aforementioned Avengers, and comics fans will likely know that Scarlet Witch uses her magical abilities to create their very own children. In the comics, the children were not raised by the couple, nor do they share their childhood together, but the twins become superheroes known as Wiccan and Speed and join the Young Avengers.

While some of the set photos for the Infinity War sequel seem to indicate there will be flashbacks, this casting call suggests could also be glances into future - or, a version of the future.
