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.
I hadn't heard of her before this thread, but I love her voice. She along with Amy Dallen (YouTube) and CommunityGirl (also YouTube). In terms of actresses, I'm not sure. I will need to think
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.
Strange how funny ladies are somehow deemed less beautiful than their dramatic counterparts.
I was watching Beetlejuice again last week, and was struck about how attractive Catherine O'Hara was around 25 years ago.
Speaking of funny ladies and 1980s Tim Burton movies, I watched Pee-wee's Big Adventure last night and I was reminded that former SNLer Jan Hooks was super-cute. (She plays the obnoxious Alamo tour guide.)
