In case you haven't already seen, heard or read enough about Zack Snyder's action-adventure-fantasy "Sucker Punch," MTV News has you covered. In addition to our [article id="1660646"]catch-all guide to the film[/article] and [article id="1660722"]secrets revealed[/article], today we bring you more from Snyder regarding the highly technical aspects of the shoot, as well as what fans can expect on the DVD and Blu-ray.

"The train sequences were the hardest technically to shoot only because it's a sequence that's broken up into maybe 120 shots that look like one shot," Snyder revealed. "So you just kind of have to know where the camera's going and where it came from, and put these little camera moves in, and all these shifts that have to happen," he said.

Snyder went on to say that he and his filmmaking team had the same sort of problems with the Samurai fight sequence, but they approached them differently.

"It was a little easier to do, but the thing that challenged us there was, of course, the scale was crazy," he said. "Ryan, who's one of my stuntmen, he would stand on a big piece of scaffolding and he would fight Emily [Browning] with this long stick," he explained. "Because she had to have an eye line to him up there. So he had this kind of flexible stick that he would try to hit her with."

Will we see any of that behind-the-scenes footage on the DVD?

"Yeah, sure," he said. "I think there is coverage of that."

Regarding what else will appear on the home-video-viewing versions of the film, Snyder teased that there will be a lot of action.

"There is about 18 minutes in the Blu-ray that is mostly action, because the MPAA was not ... [there was] a little too much action," he said, adding that taking the film from an R-rating to PG-13 was also a challenge.

"I would say that the very things that they [the MPAA] didn't like were the very things that you needed to see in order for you to understand the content of the scene," he said. "To know how to feel about it, because otherwise you're sort of left in this weird middle ground," he said. "So it's difficult. It's tricky."
