Looks like Oliver Sherman will be released on DVD in Canada on May 24. A listing for the film appeared on Amazon Canada in the last week or so.
Still no word on theatrical release for the U.S. and the rest of the world, so if you’re impatient and live in region 1 or have a region-free/NTSC-friendly DVD player (or can play unfriendly DVDs on your VLC media player), you can pre-order the film on Amazon.ca.
