As it turns out, Avengers: Age of Ultron’s battles didn’t only happen on screen.
Director Joss Whedon told Empire Film Podcast that Marvel brass weren’t thrilled with the scene in the film, in which Hawkeye (Jeremy Renner) visits his family at their farmhouse, along with the moments when the characters experience dream sequences. On the other hand, the studio was quite adamant about including the segment involving Erik (Stellan Skarsgard) joining Thor (Chris Hemsworth) in a cave.
