With the current trend of vital information surrounding something awesome and eagerly awaited being leaked online, productions companies are going to extra lengths to avoid the tiniest smidgeon of information escaping the vacuum of the film set.
Take Avengers: Age of Ultron for example. Security was so tense on set, the actors' scripts were either burnt or shredded at the end of filming everyday, as discussed by a few of the cast with BBC Newsbeat at the film's London premiere.
"Everything with Marvel is very lock and key and hush hush, you gotta sign a confidentiality agreement," revealed a bearded Chris Evans (Captain America), while Paul Bettany spoke about how the script was posted to him... with a security guard in tow, and how his name was "all over every page” so he couldn't release anything on social media.
Elizabeth Olson (Scarlet Witch) seemed in a more talkative mood about Marvel's cloak and dagger activity:
"It was quite funny that we had to burn our sides for the day... we weren't allowed to go home with our little pages of whatever we shot that day. They took it from our trailers and shredded it. It's pretty crazy."
What do you make of that?
Good idea Marvel, or are they going a little bit over the top?
