In an Instagram Live video posted on Sunday, Levi called out fans for posting fake reviews and made-up posts about Captain Marvel star Brie Larson, and asked fans to stop trying to fan flames of competition between Captain Marvel and Shazam. 

"There are people out there making defamatory and completely fictitious reviews and posts of Brie Larson's Captain Marvel -- and trying to pit Shazam against it, saying they're gonna support us and not them because of things they are making up," Levi said in the video.
