If you haven’t had a chance to see Chris Weitz’ A Better Life (with Demián Bichir and José Julián), or if you’re ready to see it again, it’s showing in its uninterrupted entirety on Showtime Thursday night at 8P…followed by a half-hour rebroadcast of a 2006 episode of Latino Filmmaker Showcase’s “Wet Foot, Dry Foot,” at 9:40P–a short in which Cuban refugees find themselves stranded on a deserted island.
