"Avengers: Endgame" directors Anthony Russo and Joseph Russo posted an open letter to Marvel fans on Tuesday, asking them not to ruin the upcoming movie for slower viewers.

"Please know that the two of us, along with everyone involved in 'Endgame,' have worked tirelessly for the last three years with the sole intention of delivering a surprising and emotionally powerful conclusion to the Infinity Saga," they wrote.

"When you see 'Endgame' in the coming weeks, please don't spoil it for others, the same way you wouldn't want it spoiled for you," they concluded. "Remember, Thanos still demands your silence."

The letter comes after footage from the highly anticipated film apparently leaked online Monday.

The footage, which has been described as "spoiler heavy," appears to have been taken down by Disney's lawyers — but quickly generated screen shots, gifs, and detailed recaps that have been circulating on Twitter and Reddit.

"Avengers: Endgame," which hits theaters on Friday, April 26, is the culmination of a decade-long series, including 22 films and a slew of intertwined superheroes.

"How we decide to put characters together is purely based on storytelling," Joe Russo said at a recent press junket. "It's not an exact science."

"We talk about so many different scenarios that we might chase down," his brother, Anthony, added. "It takes a long, a very long time to arrive at a shape."
