Paramount has set a release date for its third GI Joe film: March 27, 2020. GI Joe 3 has been in development since the release of 2013's GI Joe: Retaliation, and has gone through many phases since then. Dwayne "The Rock" Johnson has expressed interest in returning, and talk of a crossover with Transformers. However, back in March it was revealed that plans for a sequel had been scrapped in favor of a more "contemporary" GI Joe reboot that ties into Hasbro's plans to create a Marvel-like shared cinematic universe with properties like GI Joe, MASK, Micronauts, Visionaries, and Rom, a concept they've been experimenting with in the IDW comics universe.
"The world has changed, and I think you're going to see GI Joe changing with it," said Hasbro exec Simon Waters back in March, showing that Hasbro has no idea why people like GI Joe in the first place: not for modern realism, but for over-the-top insane characters, intense laser battles where no one dies, and Australian bikers high on grape soda. "There's going to be a much more contemporary approach to the whole franchise, and that will allow us to develop different characters."
In any case, these plans will apparently come to fruition in 2020, and Paramount and Hasbro will need to recast all the parts and find a director, so look for more news about this throughout 2018. Unless, of course, the movie is unceremoniously cancelled two months before it's set to be released after angering the alt-right, at which point we'll need to start all over again.
