The two-time Oscar winning director says the special 70mm version is slightly longer than the one that will be projected in multiplexes, reported Variety.
"The roadshow version has an overture and an intermission, and it will be three hours, two minutes. The multiplex version is about six minutes shorter, not counting the intermission time, which is about 12 minutes," Tarantino said.
The 52-year-old "Kill Bill" helmer wanted the 70mm version to have something extra and special, but did not want the multiplex audience to feel secondary.
"It was awesome in the bigness of 70, but sitting on your couch, maybe it's not so awesome. So I cut it up a little bit. It's a little less precious about itself," he added.
