Region 4 Winners and Losers

     The Canadian version has a 1.78:1 video aspect with a DTS-HD Master Audio and Dolby Digital 5.1 audio track. This version appears to be using the Director's cut version although I can't be certain. There are US and locally based releases also available which combine all three Butterfly Effect movies in a three disc pack or a single disc Butterfly Effect 1 and Butterfly Effect 2 combo with no extras. There seems to be considerable conflicting information on the exact specifications of the various versions available so unfortunately you'll have to take your chances if purchasing a different version from that reviewed here. On that basis I think this locally sourced version is your best option although an inclusion of an optional Director's Cut version would have been nice.
