The original plan for Deadpool & Wolverine:
The movie was supposed to start with the TVA arresting Wade for messing with Cable's time machine. While he's in their prison, he overhears that the TVA is looking to recruit Anchor Beings from across the multiverse to create an army to fight the Kangs, and they were supposed to be searching for a version of Logan. Wade decides to escape and find that Ultimate Logan before they do, bringing him to his world to be his best friend forever since he tried to be BFFs with him for years but the one from his world is now dead. From there, the plot is pretty similar to what we got, with them traveling through the multiverse (which would also give a more logical explanation for the scene at Avengers Tower with Happy Hogan), In the end, they still end up in The Void, and from there, it mostly follows the same path. Johnny Storm talking shit about Cassandra Nova was the original ending, while the original post-credits scene was supposed to be Deadpool returning to Avengers Tower and finally getting to meet Tony Stark, who rejects him.
