There's Michael and Kirk Douglas (shudder). There's Judy Garland and Liza Minelli (shudder-shudder). And of course there's the Baldwin brothers (shudder-shudder-shudder, puke). But what about the GOOD families? The Wilson brothers. Jerry and Ben Stiller. Joaquin and River Phoenix. Who else?
Sheene/Estevez? Beau/Jeff Bridges? Ralph/Joseph Fiennes? Joan/Ann/Jon Cusack? Mary Kate/Ashley Olson? (Bwahahahaha) Can't think of anymore...
