10 Things You Need To Know About Avengers: Infinity War
4. Actors Didn't Receive Scripts Before Shooting Began
Somewhat ridiculously, by the time shooting began on January 23rd, numerous cast members had yet to receive scripts, most vocally Elizabeth Olsen, Jeremy Renner and Dave Bautista, and in early January Chris Hemsworth also confirmed he hadn't read anything yet.
While for just about any other production this would be cause for alarm bells, when it comes to Marvel this is actually pretty standard fare in order to ensure secrecy, and Hemsworth himself put it perfectly: "[It’s] a little nerve-racking a couple weeks out, isn’t it? But this is the way Marvel does it."
While it's far from ideal for any actor trying to prepare for a part, it's a method that's worked well so far, so one can't knock it too much.
