I'm watching 'The Thin Man' at this very moment...
...and I can't believe, with all the threads saying who Gretchen Mol looks like, noone has mentioned Myrna Loy! In fact, judging by the way Ms. Loy looks in 'TM', Gretchen could be her reincarnation. And I could think of no higher compliment I could pay her...well, besides the fact that she is AMAZING in 'Boardwalk Empire'! She MUST be a classic beauty if she looks like Myrna Loy (IMO), and comes off so well in a show based not long before Ms. Loy's career got started.
"How do you feel?"
"Like the Kling-Klang King of the Rim-Ram Room!"
