“Avengers: Age of Infinity” may feature another villain other than Thanos. Though the film isn't set to release until 2018, auditions for the role of the evil Magus are already underway, Acting-Auditions reported.

“The auditions for new lead and supporting roles will be taking place in Los Angeles, CA. The film is the first in a two-part sequel in which Thanos plays a major role, along with the Magus,” reads the report. Though there is no official confirmation, the website reports that Magus will assemble the Infinity Gauntlet after he separates from his own body. His alter ego will be Adam Warlock. To create havoc on Earth he will create doppelgangers of the Avengers.

In the comics, Magus first appeared in “Fantastic Four” as Him. He was revamped as Warlock in "Marvel Premiere" No. 1. He is a messiah who can manipulate energy and has the ability of fly.

It has also been reported that film will star that Tom Hiddleston as Loki, who was left out of “Avengers: Age of Ultron,” as the film had too many characters. "We did shoot something, but it didn’t play. The movie has so much. It’s so filled. We didn’t want it to feel overstuffed. I really wanted to have Loki in it, but I understood the decision that there were now too many voices in the chorus,” director Joss Whedon told MTV.

“Avengers: Age of Infinity” will be made in two parts and will be set after the events of “Captain America: Civil War.” Josh Brolin will play Thanos and it is set to revolve around Infinity Gauntlet. Anthony Russo and Joe Russo will direct from a screenplay by Christopher Markus and Stephen McFeely. “Avengers: Age of Infinity - Part 1" opens May 4, 2018, and “Avengers: Infinity War - Part 2” opens May 3, 2019.
