Avengers: Endgame is one of the biggest movies of all time. It’s dynamic storylines and characters kept us on our toes the entire three hours of the film, so it’d probably be a lot for creatures to make such a complex film.

Endgame screenwriters Christopher Markus and Stephen McFeely have written many films in the Marvel Cinematic Universe, which is a challenge.

Now, they’ve opened up about the hardest part about writing both Avengers: Infinity War and Endgame.

"We were nervous at that moment because it was such a big project," McFeely said to Variety. "It would take up so much of our lives and it would be the biggest puzzle that we ever would put together as writers. That was scary and we we said okay, we should probably do scary things and if successful, it might be really amazing."

"We knew this would never come around again,” Markus added.” For someone to offer you the culmination of this big of an undertaking, that’s never going to happen again. And as consuming and sometimes painful as it was over the past four and a half years that we’ve been working on it, it will never happen again. To walk away from it would seem like something that you’re really going to kick yourself about later."

The pair also recently opened up about the scene in Captain America: The Winter Soldier where viewers find out that Captain America’s love interest, Peggy Carter, is married with two children.

The writers have now explained that the man she was married to was Captain America himself and the kids are his. The idea is that she married Captain America from the main MCU timeline prior to him going `back in time at the end of the movie.

Although future plans are not set-in-stone, McFeely says that it was their “intention that he was always the father of those two children.”

“There is some conversation to be had on this,” he continued. “Quantum physics works in interesting ways, and what Marvel chooses to do is not up to us but … it was our intention that he was always the father of those two children. But again, there are time travel loopholes for that.”

The idea that the children belong to the character brings up the idea that “there are two children who have somewhat super soldier DNA,” Markus said.

Other Avengers: Endgame news

Avengers: Endgame finally got a post-credit scene two weeks after its debut — the latest trailer for Spider-Man: Far From Home.

The Russo brothers opened up to fans on the Happy Sad Confused podcast about why a scene with  13 Reasons Why star Katherine Langford was cut from the film. But be warned — there are a lot of spoilers there too.

Outside of the worldwide record, it also beat Titanic domestically with $619.7 million.

The highest-grossing movie ever was Avatar at $2.788 billion worldwide, so we’ll have to wait to see if the Avengers can beat that.

Avengers: Endgame has beaten many records since even before its debut. For one, it sold five times as many tickets as Infinity War during its first week of presales. This should come as no surprise with the demand of tickets being crazy enough for fans to spend upward of $15,000 for a pair.

Also, the film broke the record for Atom Tickets’ best-selling movie of all time in only 10 days.

Once it premiered, the records only kept coming. It officially had the biggest box office weekend in film history.
