Oh, I'd watch it too (throw Nastassja in for good measure, since I wanted to marry her for several years after seeing Tess in 1979). That would be two DVD rentals total. I don't think they'd make their money back.
Any film collaboration with Rip Torn should be approached with great caution. Ask Norman Mailer, who had Torn appear in his film "Maidstone" and as I recall Torn had the clever idea of hitting Mailer on the head with a hammer and then biting off part of Mailer's ear.
Having watched this video, I feel Mandy Patinkin could act Bukowski quite successfully. I think his voice is very similar to Hank's. Even his hair :) And if I compare him to the other actors performed Bukowski, he's on the top of my list.
