I just saw The Savages (2007, now on DVD), and it's pretty plain to me that Tamara Jenkins, who both wrote and directed the film, well deserved the Academy Award for best original screenplay (she lost to Diablo Cody, who wrote Juno). Like, say, Sideways, The Savages is a film for grown-ups. The story focuses on siblings who must decide what to do about (or for, or with) a parent who's failing. Philip Seymour Hoffman and Laura Linney offer brilliant performances as Jon and Wendy (apt names!), adult children trying to do the right thing, still caught in the bickering and rivalry and emotional distance of a dark childhood. Philip Bosco is their father Lenny, a man whose anger and intolerance remain frightening even as he passes into dementia. A brief scene late in the movie gives an idea of what he was like in earlier years.
Here's one bit of dialogue, when Jon and Wendy find their father tethered to a hospital bed:
Lenny: So do something! You're the doctor!
Jon: I'm gonna go get somebody.
Wendy: He's not that kind of doctor, Dad.
Lenny: I thought he was a doctor.
Wendy: A doctor of philosophy. He's a professor, of theater.
Lenny: Like Broadway?
Wendy: No, Dad, like theater of social unrest.
