Throughout "Edge of Tomorrow," both the film's protagonist and the audience are constantly returning to a massive battle between humans and alien invaders on a beach. Per the Los Angeles Times, this expansive set piece was always meant to be a big commitment on the part of the cast and crew. However, that commitment was originally supposed to entail just two weeks. Instead, it ended up going on and on for almost three months. The constant delays stemmed from Liman improvising and making new stuff up as he went along.
As if that wasn't enough of a challenge, the movie's big beach scene was filmed on a manmade location. This expansive set took a lot of effort to keep functioning over a solitary day, let alone over multiple months. Having to keep this set in working order, not to mention Emily Blunt almost breaking her nose during all this, meant that filming this battle sequence was a trying experience unto itself. At least everyone involved can comfort themselves knowing that all the blood, sweat, and tears did result in an immensely tangible sci-fi set piece.
