In October 2017, Marvel Cinematic Universe actor Mark Ruffalo rather infamously accidentally live-streamed the opening minutes of Thor: Ragnarok during the film's Los Angeles premiere after forgetting to turn off his phone's Instagram live feature. Later, the actor would reveal the goof put him in the hot seat with Disney, considering 2,500 of his followers heard the first 20 minutes of the Thor threequel over a month before the film's worldwide release.

However, it seems like it's all water under the bridge now. In a retrospective interview with Entertainment Weekly, the cast of the highly anticipated Avengers: Endgame addressed Ruffalo's Ragnarok leak.

"That was the one that got me the call from up high," Ruffalo recalled.

However, the actor's Ragnarok co-star Chris Hemsworth was quick to reveal the mistake was actually a stroke of genius. "Wait, wait, that was actually genius! There might be some strategy there, because [the audience] laughed so hard during that [footage]. All [viewers] could hear was laughing. They went, “It must be good!"

"It sort of turned around on me," Ruffalo continued, "because when I came to work on Monday [on the set of Endgame] everyone ran up to me. I thought they were coming to scream at me — Barry [Curtis], he threw his arms around me. “That was genius! We got more press than we could have possibly paid for!"

Marvel Studios President Kevin Feige then added, "Yes, Barry Curtis, our supreme security at Marvel Studios, who now is immortalized as the Blockbuster parking-lot security guard in Captain Marvel."

Alongside Tom Holland, who plays Peter Parker/Spider-Man in the MCU, Ruffalo has earned himself a reputation as one of the more dangerous cast members when it comes to potential spoiler leaks. The actor actually spoiled the shocking ending of Avengers: Infinity War a year before the film's release, and part of an interview on The Tonight Show Starring Jimmy Fallon had to be bleeped out of the broadcast when Ruffalo accidentally revealed what some believed to be the Avengers 4 title.
