Owing to the memes and videos of the portal scene from Avengers: Endgame featuring multiple characters from all over pop-culture, I thought up a movie based on it. It's a pipe-dream of course, but still fun to think about.
Title: The Endwar
Approx release date: Sometime in 2030
Plot: Thanos and Darkseid have fused into one being - Thanoseid, and desire to unmake all of creation. With their armies of Outriders, Parademons, Chitauri and more at their command, all of the omniverse is under threat. The time has come for all peoples and creatures of the omniverse, hero and villain, to stand as one.
Look: 100% CGI, because face it; by 2030, CGI will be borderline realistic, if not full-on able to fool most people. Think MK11 and Injustice 2, but even better.
Cast: Far too long to list everyone. Almost anyone you can think of will be there, no matter how obscure. Chuck Norris himself won't feature, but his various roles will (Expendables, Invasion USA, etc). All the MCU and DCEU of course. A various myriad of video-game characters, and other comic book characters such as those from Image and Dark Horse. Godzilla will star as well; all of them. The Spiderverse. You name it, this movie will probably star them.
Expected box-office return (that the way to say it?): Ten billion dollars at the very least. Definitely more given how much CGI will have to be rendered.
