Just last week, Sigourney Weaver teased that she was watching a lot of Marvel movies and TV shows. At the time, no one knew why she made the statement, but it sure had a lot of fans speculating that the iconic actress may have joined the MCU. Today, we have a confirmation that this is very much true. And she is set to play a key role in this cinematic universe.

That's right, the legendary actress, known for such hit movies as Alien and Ghostbusters, is officially a member of the Marvel family. And she will be making her presence known in the upcoming Netflix miniseries The Defenders. The show already has a stellar ensemble cast, with the leads from all four main Marvel Netflix shows appearing together.
