There have been speculations going around that Tony Stark may make a cameo appearance on the upcoming "Doctor Strange" film. This rumor was led by the events of the recent Marvel movie and a mysterious tweet about the alleged cameo.
A tweet "confirming" Tony Stark's appearance in the film
It can be recalled on the last movie, "Captain America: Civil War," that Tony Stark may be in need of a new set of allies. Many of them have already cut ties with him ever since the Avengers dissolved. In addition to that, Stark recruited another superhero to have ties with him, Spiderman. This has then led to the assumptions that he may be making an appearance on "Doctor Strange."
The speculations don't end there. According to Comic Book, there has been a post on Twitter saying that some "little spies" informed the account user that Tony Stark may have a cameo on Doctor Strange. Of course, this post is not official as it was not posted by anyone of the production staff of the film. There is little to this information, but Marvel fans definitely looked more into it.
Movie's wrap up moved a couple of months
Another factor that has fed to these speculations is a tweet made by actor Benedict Wong posted a few days ago, saying they just wrapped up the movie. However, it has already been known that "Doctor Strange" already wrapped-up filming the movie months ago, as reported by Cinema Blend. Assumptions were then made that there were additional scenes for the film that were shot, involving Tony Stark's cameo appearance.
Avid fans of the show see great significance if and when Tony Stark does make an appearance in the upcoming film. Since "Doctor Strange" is set to feature a different kind of Marvel movie involving mystical powers, the appearance of Tony Stark, who is a master in scientific knowledge, will definitely clash with the ideas of Doctor Strange.
