For people who have followed the Marvel Cinematic Universe for a decade now, its latest installment – Avengers: Endgame – was an emotional experience. It makes sense that for the actors who have embodied these roles for years, it would be as well. It’s probably why while filming the last movie, Robert Downey Jr. – aka Iron Man – did something nice for his co-workers. He threw them a lunch, which included a mariachi band playing “La Bamba.”

The video features the cast alternating clapping and eating as the mariachis sing the iconic song in a tent adorned by papel picado. The best part of the whole clip is when a bearded Chris Hemsworth, who is standing outside, starts doing a silly dance. Nobody ended up dancing with him, though, but Chris was living his best life.
