Last night, we saw Kate Mulgrew (Capt. Janeway) at the A.R.T. in Tea at Five, a one-woman show about Katherine Hepburn. Matthew Lombardo's play is, perhaps, rather slight, but Mulgrew is a phenomenal Hepburn. One act is set in 1938; she gets the voice right and the movement exactly. The second act is set in 1983, and again she gets the voice, the sense of soldiering on, and the gesture: an impressive technical display.
