Since the digital release of Avengers: Endgame, fans have been watching and re-watching the film, looking for details and clues that they might have missed on the big screen.

To celebrate the release, directors Joe and Anthony Russo participated in an Ask Me Anything (AMA) session on Reddit, CBR reports. Among the many questions the brothers answered, one stood out as the most intriguing when a fan asked if there were any “important” Easter eggs yet to be found in the film.

The directors answered simply, “Yes.”

There is no doubt that the brothers’ confirmation has sent people back into the film with a fine-toothed comb. What could the Easter eggs be about? The future of Marvel Studios' Phase 4 films? The possibilities are truly endless for this franchise. Time for the hunt to (re)begin!
