My favorite Dorothy Parkerism was her famous pan of a Katherine Hepburn (no less!) stage performance:

"Miss Hepburn ran the entire gamut of emotions from A to B."

There's another zinger, I've been told, in a review of a new Kathryn Hepburn play, eagerly awaited by the multitudes licking their chops waiting to see just what scathing comment might come forth this time.

The review, when it appeared, was long and laboriously detailed, praising all aspects of the production but making no reference at all of KH.

Until the very end, where it concluded, "Miss Hepburn's performance was not up to its usual standard." [wince] - because we know just how abysmal was Dorothy Parker's opinion of Kathryn Hepburn's "usual standard"...
