Hollywood stars Mark Ruffalo and Robert Downey Jr took to social media to celebrate the second anniversary of Avengers: Endgame, the final chapter of the superhero franchise.

Ruffalo, who plays Bruce Banner aka the Hulk, took to Instagram to look back at the historic film that led to major changes in the Marvel Cinematic Universe.

"Can't believe it's been two years since the premiere of Avengers: Endgame," Ruffalo wrote on Instagram, sharing a photo of himself with co-stars Chris Hemsworth, Chris Evans, Robert Downey Jr, Scarlett Johansson, and Jeremy Renner. "Love you all 3000," he added, referring to the emotional and now viral dialogue, first said by Downey Jr's Tony Stark.

Meanwhile, the Russo brothers, Anthony and Joe, commemorated the occasion by sharing behind-the-scene pictures of the cast. "Two years since the release of Endgame. Which theater did you see it in for the first time?" they asked on Instagram.

Many actors have continued their MCU journey on the small screen, with Elizabeth Olsen and Paul Bettany starring in WandaVision and Anthony Mackie and Stan in The Falcon and the Winter Soldier.
