Unless I'm mistaken, that's Melanie Lynskey, who debuted alongside Kate Winslet in Peter Jackson's Heavenly Creatures but hasn't gone on to such an illustrious career. She's had small parts in plenty of movies but hasn't yet achieved stardom.
And was a regular on Two and a Half Men for a few years. She was actually one of the (few) reasons I watched that series.
The first crush I ever had at age nine was Mariette Hartley after seeing her Trek episode, which is why I then in subsequent years never missed an episode of her short-lived sitcom "Goodnight Beantown" with Bill Bixby.
