Move over Lord of the Rings movies, you’ve got some competition when it comes to epic run time.

“The running time on Avengers 4 is currently sitting right at three hours. We’ll see if that holds,” director Joe Russo said during an Instagram chat promoting his new downtown Los Angeles Bar, Duello. Although a three-hour-run time would make Avengers 4 the longest Marvel Cinematic Universe film ever, beating out its predecessor Avengers: Infinity War (2h40mins) and Captain America: Civil War (2h27mins), the current three hour is tentative.

“We’re about halfway through the editing process,” Russo continued. “We’re really just scratching the surface on our VFX shots. There are more than 3,000 VFX shots in the movie; those require a lot of time and thought and energy and effort, and we’re very early in the phase of getting VFX done. We’ve just started work with Alan Silvestri on the score, and we’re still editing picture at this point.”

Although the Russo Bros. and the Avengers 4 production have been reticent when it comes to spilling any major details or secrets about the highly-anticipated film (besides cryptic, on-set allusions), Russo did confirm the film’s longer run time will correlate to paramount significance. “Will the stakes be higher in Avengers 4? Absolutely. 100 percent,” Russo said. “The highest of any of the films to date, without question.”

Avengers 4 is slated for release on May 3, 2019.
