  • Marvel took extreme measures to keep " Avengers: Infinity War" scripts a secret.
  • The cast was given fake scripts.
  • Some of the cast did have the option to read.
  • But the restrictions kept some from wanting to read it.

Marvel went through great lengths to keep the "Avengers: Infinity War" scripts a secret. The restrictions were so intense that some of the actors didn't want to deal with it.

"They offered a room to sit in and read off an iPad for five hours in a room without anything else around you," star Elizabeth Olsen said on ABC's "Jimmy Kimmel Live" Thursday. "That sounds unpleasant, so I just said, 'Can you tell me what goes on and just give me my pages?'"

Most of the "Infinity War" cast didn't even know what happened in the full movie until the premiere, because they were given fake scripts to help prevent leaks.

Paul Bettany, who plays Vision, told HeyUGuys.com that they didn't know what was real or not until talking with the directors.

"The secrecy around this film extended, this time, to the cast," he said. "We read scripts that were fake scripts and then they had fake twists and scenes that never were shot, and you'd talk to the director and they'd say, 'All of that stuff at the end? Not happening.'"

In an interview with "Total Film," Bettany said the real scripts were on three protected iPads, which some people had a chance to read.

Among the cast members who said they read the full script were Benedict Cumberbatch and Robert Downey Jr., but other cast members were deliberately kept from the script.

Tom Holland, who plays Spider-Man, was identified by some of his cast members as the " least trustworthy" while on "Jimmy Kimmel Live." He didn't even know who he was fighting in the movie because he was told he was "terrible at keeping secrets," Holland told ComicBook.

Also pegged as bad at keeping secrets is the Hulk actor Mark Ruffalo, who accidentally streamed 20 minutes of sound from "Thor: Ragnarok," when he failed to shut off his Instagram live stream.

It's no wonder Marvel goes to extreme lengths to keep their movies under wraps.
