In this fast-paced, over-connected, news-is-now era we're living in, it's a wonder when plot secrets stay under wraps until the film is released. On one hand, it's good for business when people are interested in and obsess over your upcoming movie, but on the other, it's bad when spoilers ruin well-intentioned and well-placed surprises.

When MTV News caught up with the cast and writer/director of this week's anticipated action/thriller "The Bourne Legacy," we asked them to describe the level of secrecy involved in protecting the new film, as well as the measures that were taken to avoid any plot leaks. As it turned out, everyone involved participated in a bit of stealth secret-keeping, especially leading man Jeremy Renner, who is almost a spoiler-proofing pro at this point, given his involvement in several top-secret blockbusters like "Mission: Impossible - Ghost Protocol" and "The Avengers."

" 'The Avengers' was pretty intense. This one was small in a lot of ways," Renner said, comparing his two big movies this year. "We were in a studio here [in Los Angeles] and out in the middle of nowhere, out in the Rockies. It wasn't until we were shooting in Manila and surrounded by thousands and thousands of people being spectators that you had to be protective, but not nearly as much as with 'Avengers.' I guess it was more so the script and trying to keep that under wraps and protect the franchise."

"They came and gave me the script, and Tony's assistant waited for me to finish it outside my room," added co-star Rachel Weisz. "It's as paranoid as the movie is. Becoming a part of them is very secretive."

Writer/director Tony Gilroy found the secret-keeping ironic at first — until it required him to write almost an entire other movie.

"You go through your whole [career] as a writer, and all you want is for people to read your script. 'Please read my script, please read my script!' And then I end up on this movie after 30 years, and no one is allowed to read the script," Gilroy recalled with a chuckle. "It's in a safe that the department heads have to come and check out. It's really crazy. The weirdest thing, I had to write fake scenes for actors to audition. I ended up almost having to write a parallel script, much more than I ever thought, lots of different scenes, so we could have people come in and audition and not blow the movie. That's another new odd facet of mega-moviemaking."
