When you have a movie as big as Avengers: Endgame, which is spawned out of a decade-long MCU (Marvel Cinematic Universe), there will always be thousands of fan theories attached. Ever since Avengers: Infinity War (2018), fans have been on overdrive trying to decipher what will happen in Endgame. When the trailers of Endgame started coming out, fans theorised the use of time travel as well as the quantum realm to defeat Thanos and bring back the ones lost during Infinity War.One ludicrous but extremely popular theory involves Ant-Man and Thanos. According to this theory, a shrunk Ant-Man will enter the rear end of Thanos and grow inside him. In the process, Thanos will be killed. This theory instantly caught on like wildfire and Paul Rudd was asked about the same while promoting Avengers: Endgame on Jimmy Kimmel Live!. When Jimmy posed the theory to Paul, he slyly quipped, “Similar to your dream, one light difference.” Did Paul just confirm that Ant-Man plays a big part in defeating Thanos? It certainly looks like it.
Avengers: Endgame stars Robert Downey Jr., Mark Ruffalo, Chris Evans, Chris Hemsworth, Scarlett Johansson, Jeremy Renner and Brie Larson, amongst others. Directed by The Russo Brothers (Joe Russo, Anthony Russo), Avengers: Endgame delves into the after-effects of Avengers: Infinity War and how the remaining superheroes go on a quest to avenge the fallen, whatever it takes!
