An older version of Ant-Man’s daughter, Cassie Lang, will be in Avengers 4. All eyes are on the Marvel Cinematic Universe right now. Marvel Studios is just a few days away from the world premiere of Avengers: Infinity War, and then just a few more from its global release. Fans know that the movie will see Thanos finally arrive to torment every hero in the MCU. But, directors Joe and Anthony Russo are asking everyone to avoid spoiling the movie’s plot at all costs, which only adds to the uncertainty of Avengers 4.
That Hashtag Show reports that Emma Fuhrmann joined the cast of Avengers 4 and that she plays Cassie Lang. Fuhrmann is still a new talent in Hollywood, but she appeared in Blended alongside Drew Barrymore and Adam Sandler in 2014. Her casting is still just rumored, even though THS‘s sources confirmed her role after she appeared on IMDb. But, some further evidence could be found on Fuhrmann’s social media where she shares a lot of Marvel promos, and shared a picture featuring a bottle with the Avengers logo on it.
