The Last 3 Minutes is a beautiful short film by cinematographer Shane Hurlbut, the cinematographer of Terminator Salvation. It was shot using the Canon 5D Mark II, and was sponsored by Canon to show off the latest firmware that enables 24p (frames per second) recording, giving it a “movie quality”. Filming spanned 17 locations across 4 1/2 days, and a wide assortment of Canon prime L lenses were used.
The present day portion of the film in the beginning was shot at 24p, while the flashbacks were filmed at 30p and converted to 24p in order to produce a dreamlike quality. You can read more about how the film was made on Hurlbut’s blog.
