I couldn't agree more about Gleeson, and I'd love to see both of those. They're not available on DVD, so Netflix is no help. I Went Down has a VHS release. Saltwater is McPherson's adaptation of his own play; but nine years after the movie's release, is it likely to come out on DVD now? Probably not.
Gleeson is in three movies due for release this year: Perrier's Bounty, Green Zone, Into the Storm. He plays Winston Churchill in the last one.
