According to the anonymous Wikipedant, Tara Fitzgerald is currently appearing at the Globe Theatre as Lady Macbeth. Makes sense to me. (Also at the Globe, she’s played Hermione in A Winter’s Tale.) Now fifty-one, she has an enormous string of credits, and occasional portraits therefrom.
In the States, you may remember her as Selyse Florent over three seasons of Game of Thrones.
A look at herself, from the Guardian, a few years back:
And she played Topaz Mortmain, Cassandra’s seemingly self-absorbed stepmother, in Tim Fywell’s 2003 film of Dodie Smith’s I Capture the Castle, which pretty much demands that she be here somewhere.
