The latest revival of 'The Heiress' has done the near impossible - it's drained the light from one of the most luminous actresses working today. In a good way. Jessica Chastain, that ravishing redhead with the milky skin who shot a dose of bubbly charm to the film 'The Help,' turns almost ghoulish in the title role…What's left is a skittish woman with hollow eyes, a simply horrible hostess who, when she speaks, does so in a dull monotone. Even her hair looks mousy. Full credit goes to Chastain, who has buried herself in dullness to play one of theater's more formidable proto-feminist roles. The men in her life - David Strathairn plays her father and Dan Stevens of 'Downton Abbey' her suitor - aren't too shabby either, each turning in performances that are complex and sympathetic. Neither actor, under the superb, subtle direction of Moises Kaufman, emerges as a straw man.
