then that Whannell realized that they didn't have money left in the budget to hire a stuntman to shoot the scene, forcing him to perform the scene himself. It took six days to shoot all the scenes in the bathroom, and these were filmed chronologically to avoid continuity jumps and help the actors stay in character. To film the scenes of the two protagonists, Wan made sure most of Dr. Gordon's shots were very steady and controlled while Adam's shots were shaky and handheld to match the characters' personalities. Instead of using a camera dolly or a tripod, cinematographer David A. Armstrong shot the entire film with the camera over his shoulder. There was not time for Elwes and Whannell to rehearse their scenes together to not conflict with the schedules of Danny Glover and Michael Emerson, who were only available for a certain number of days. Glover completed his scenes in two days. According to Elwes, his dialogue averaged 12 to 16 pages a day, which he considered a great challenge. Due to the tight shooting schedule, Wan could not afford to shoot more than a couple of takes per actor. "It was a really tough struggle for me. Every day, it was me fighting to get the shots I did not get. I had high aspirations, but there's only so much you can do. I wanted to make it in a very Hitchcockian style of filmmaking, but that style of filmmaking takes time to set up and so on", Wan said about the very short shooting schedule. He said the style instead ended up being "more gritty and rough around the edges due to the lack of time and money that we had to shoot the movie with" and it ultimately became the aesthetic of the film. $400 were spent on reshoots Wan and Whannell did on their own. For the reshoots, Whannell served as a stand-in to Smith and Ken Leung in the scenes of Amanda searching for her key and of Steven Sing entering into Jigsaw's lair. In post-production, Wan found he did not have enough shots or takes to work with as he was basically shooting rehearsals. Having a lot of missing gaps in the final product, he and editor Kevin Greutert created shots to mend together during editing, such as making a shot look like a surveillance camera feed and using still photographs.
