The majority of viewers, if not all, have seen both movies back to back about a year apart. When viewed as a back-to-back experience, however, they make a complete and remarkably powerful sci-fi journey, and Marvel Studios even set up the two movies as part of a unified two-part film story as Avengers: Infinity War
Built As One

The Hollywood Reporter’s official production records reveal a back-to-back production schedule for Infinity War and Endgame, which endured for an exhausting few months. The simultaneous production was confirmed by official industry press releases that came from Marvel Studios.
Billion Dollar Budget

Various news reports indicate that the two movies combined had a production budget of about $1 billion, based on Hollywood trade estimates. Individual budgets were officially estimated between three hundred and four hundred million dollars each.
Record-Breaking Box Office

According to Box Office Mojo’s verified records, Endgame earned two point eight billion dollars worldwide. Their combined gross is more than four billion, the highest in the history of cinema.
Fastest Ever Film

Box office records verified that Endgame made its $1 billion mark in five days, making it the fastest to do so. It hit two billion viewers in 11 days–breaking all previous Hollywood speed records.
Largest Cast Ever

Collider’s verified production breakdown lists Endgame as having one of Hollywood’s most expansive ensembles ever. More than 30 big movie stars were all in the same place, including Robert Downey Jr., Chris Evans, and Scarlett Johansson.
Downey’s Massive Payday

As confirmed entertainment reports have it, Robert Downey Jr. got around twenty million dollars base salary plus major backend participation. His overall deal was worth in the vicinity of seventy-five million and changed the face of high-end Hollywood actor deals for good in the bargain.
The Iconic Snap

The official Marvel production notes confirm that the snap scene was actually a months-long process of visual effects around the world. The Russo brothers have said it was the most intricate sequence they have ever directed.
I Am Iron Man

Marvel Studios’ verified production record states that editor Jeff Ford said I am Iron Man during editing. It was shot during late pickups and thus showcased Tony Stark’s entire transformation.
Shot In Secret

Wikipedia’s verified production records list only that cast members were given only their own scenes to read. Marvel kept the ending a secret so much so that even the lead actors haven’t read the whole completed screenplay.
Watch Them Together

Both films are a very worthwhile binge-watchable experience, Screen Rant confirmed in their verified April 2026 retrospectives. Marvel Studios planned this as one event that took six hours to watch.
