Most of the world won’t see “Avengers: Endgame” until April, but a few lucky moviegoers got to be members of test audiences. Directors Joe and Anthony Russo revealed that audiences have been loving the new Marvel Studios flick.

“Right now, we think the movie is playing well and we’ve had great responses from our test audiences and we’re feeling very good about where it is,” Joe Russo told Collider.

The movie is still being edited, but it’s currently about three hours long. Though the brothers have joked about intermission, the test audiences have indicated that they can sit through a long movie. They’ve had four test audiences so far, and only one had people standing up.

“For the first three screenings, not a single person got up to go to the bathroom,” Anthony Russo revealed.

They think Marvel Studios would be fine with “Avengers: Endgame” being three hours long. Though they aren’t finished with the movie yet, they know that they need extra time to tell a story this big.

“We’re still doing work to it. We’re not done with it,” Joe emphasized. “Again, this is a culmination film of 22 movies, it’s a lot of storytelling to work into it. Emotion is an intrinsic part of that to us. When you have to tell a really complicated story and you want strong emotional moments with the characters, it just requires a certain amount of real estate. This one, in particular, feels like three hours worth of real estate.”

The test audiences are the only fans who have a real idea of what the movie is about. “Avengers: Endgame” has had two trailers thus far, but neither reveals much about the plot.

It’s clear that the heroes are still reeling after “Avengers: Infinity War” ended with half of all life disappearing. The Earth-bound characters are definitely on a mission to bring their friends back while Iron Man (Robert Downey Jr.) is stranded on the Benatar with Nebula (Karen Gillan). Beyond that, not much has been confirmed. Fans figure that Captain Marvel will somehow factor into the plot, but details haven’t been revealed.

“Avengers: Endgame” hits theaters April 26.
