Jacqueline McKenzie puts her feline heart into Cat on a Hot Tin Roof IN the winter of 1994, a small group of actors gathered at a cold, draughty church in Darlinghurst, in inner-city Sydney. They were there to rehearse Hamlet under the direction of Neil Armfield. The troupe included some of the biggest names of the contemporary Australian stage: Geoffrey Rush, David Wenham, Richard Roxburgh and Gillian Jones - "perhaps one of Australia's greatest actresses," recounts Jacqueline McKenzie through a mouthful of salad during lunch break in rehearsals at Belvoir St Theatre last month.
