SPOILER ALERT! John Krasinski's name has been connected to the upcoming "Doctor Strange and the Multiverse of Madness," and it hyped the fans even more!

Less than a week before "Doctor Strange and the Multiverse of Madness" premieres, MCU fans had a pre-party after a leaked cameo role of Krasinski emerged.

In since-deleted posts on Twitter and Instagram, it was revealed that Krasinski is about to play the role of Mister Fantastic. The grainy video was reportedly from the upcoming "Doctor Strange" trailer.

Although the new video spoiled the fans, it is worth noting that they wished for him to play the role by creating several fanarts showing the actor playing the role of Reed Richards.

In the video, Krasinski sports his blue costume while facing Elizabeth Olsen's Wanda.

Three other heroes trail after him, who make up the Illuminati. It includes Captain Marvel (not Brie Larson), Black Bolt, and Captain Carter (British Captain America).

With the emergence of the clip, Forbes shared a few questions that could stir fans' curiosities, including whether Krasinski's Reed Richards is just a variant or if the actor would also serve as the director of the film while starring in it.

Fans Already Welcoming John Krasinski to the Franchise!
