The 37th film in the Marvel Cinematic Universe - the first of phase six - lands in UK cinemas from Thursday, so we hope you've been keeping up.
The Fantastic Four: First Steps stars Pedro Pascal as Mister Fantastic, Vanessa Kirby as The Invisible Woman, Joseph Quinn as the Human Torch and Ebon Moss-Bachrach as The Thing - complete with his catchphrase: "It's clobberin' time!"
Set in the 1960s, the films sees the heroes forced to defend Earth from a hungry space god named Galactus, played by Ralph Ineson, and the Silver Surfer, played by Julia Garner.
But don't worry if you haven't seen all or any of the previous 36 MCU films, as director Matt Shakman says his latest attempt to bring comic book heroes to the big screen exists in its "own universe".
"There's really no [other] superheroes," he told Empire. "There's no Easter eggs. There's no running into Iron Man or whatever. They're it, in this universe. I love the interconnected Marvel Universe, but we get to do something so new and so different. Eventually, this world will meet up with other worlds - but for now this is our own little corner."
John Malkovich was due to appear in the film as Red Ghost, however Shakman told Variety it was "heart-breaking" to ultimately have to leave his scenes on the cutting room floor.
