In a new behind-the-scenes featurette for Marvel's "Avengers: Age of Ultron," the cast and crew took some time out of their busy schedule to talk about the atmosphere on set.
With a smile on his face, director Joss Whedon described the camaraderie between the cast members as "an exhausting delight" over footage of the actors joking around on set.
"It's like summer camp," "Captain America" star Chris Evans agreed. "It doesn't feel like work at all."
