Diane Keaton Demonstrates Her Shriek-ability has assembled a must-see video mashup of one of our favorite post 50s, Diane Keaton, shrieking. Yes, shrieking -- from spazzing over her 20-something daughter's marriage in "Father of the Bride" to freaking out at the discovery of a corpse in "Manhattan Murder Mystery." We didn't realize the star of "Darling Companion," which opens today, had such an enormous vocal range when it comes to shrieks -- so kudos to for opening our eyes to this overlooked talent. Check out the mashup above and see if you agree.
