Spit Spignola, I'm replying to one your most recent top-level comment because I wanted you to know that if you want to bug Criterion about releasing a DVD of Phase IV, their contact page says: "To suggest a title, please write to suggestions@criterion.com".
I emailed them around the time I posted that reply. A seperate email from someone else would help the film's chances. Don't forget to mention the inimitable Saul Bass.
