The Russo Brothers are filming both Doomsday and Secret Wars back-to-back. The video concludes by promising more updates on teasers and Easter eggs, and mentions potential new footage for Spider-Man: Brand New Day.

The video introduces a new Avengers Doomsday trailer premiered at Destination D23. It highlights the leaked, potato-quality footage and plans to break down the trailer clips throughout the video, including mention of 1940s cars suggesting Captain America and Peggy Carter's return, and confirms Chris Evans' involvement.

The Russo Brothers show off their behind-the-scenes trailer, featuring new footage and Paul Rudd's Ant-Man. The trailer begins with the Marvel Studios fanfare, interrupted by Thor saying, 'We can put together the greatest team ever.' This is followed by a clip of Sam Wilson saying, 'If we can't see the good in each other, we've already lost the fight,' hinting at internal conflicts among the new Avengers teams.

Shuri appears, stating, 'Now is our time to strike,' implying her more aggressive role, potentially alongside Fantastic Four characters and other new Avengers. Ant-Man's clip, 'Will I be there when the Avengers need me? Absolutely,' confirms his involvement. Yelena Belova's line, 'We stick together from now on,' suggests her role in uniting the disparate superhero teams.

Falcon (Torres) expresses his desire for responsibility, 'That pressure, that responsibility, I want that too,' hinting at his upgrade and inclusion in Sam Wilson's new Avengers team. Red Guardian's line, 'This has the makings of a team that can bring light from the darkness,' indicates his enthusiasm for being part of the new Avengers teams in Doomsday.

God Loki's dialogue, 'Raising things to the ground is easy. Trying to fix what's broken is hard,' alludes to the multiverse breaking in Avengers Doomsday and Secret Wars, with discussions about Sylvie's potential appearance. Professor X's line about an incoming war (mutant and human) and Cyclops's protective statement tease the X-Men's significant role and potential threats to key characters.

Reed Richards's line, 'Today we are your defenders, we will protect you,' from the Fantastic Four movie suggests their involvement and a visit to their universe. Shuri gives the Wakandan war cry, hyping the battle against Doctor Doom's team.

The Russo Brothers confirm they are shooting Avengers Doomsday in London, emphasizing the massive scale of the film. They state, 'We're bringing together so many of your favorite heroes to face one of Earth's greatest threats in the MCU, Doctor Doom,' highlighting his central antagonist role.

Paul Rudd makes a humorous cameo, acting as if he's stopping the Russo Brothers from revealing spoilers and blocking views of the set. The video explains that this is a strategic behind-the-scenes trailer, similar to those for Infinity War and Endgame, designed to tease without giving away too much.

The 1940s footage of Captain America and Peggy Carter might involve God Loki, tying into Endgame's continuity. The video dispels rumors of a feud between Robert Downey Jr. and Ryan Reynolds, clarifying they have never filmed together or met in person.
