Mark Ruffalo says he was forced to film five endings for Avengers: Endgame because directors were so worried he would ruin the surprise. During an interview to E! News, Ruffalo, who plays Hulk for the series, said directors Joe and Anthony Russo did not want him to know the ending, reports dailymail.co.uk.

"I don't know what's going to happen," Ruffalo said, adding: "I shot, like, five different endings to this movie." He continued: "I didn't even get a whole script to this movie. And I don't know why. The script I did get had dummy scenes in it."
