I've only seen Marilyn in Gentleman Prefer Blondes and The Seven Year Itch.
I liked her in Itch, but I came away from Blondes wondering what the Monroe fuss was all about, not to mention, a huge crush on Jane Russell.
Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day; begin it well and serenely and with too high a spirit to be enbered with your old nonsense. ~ Emerson
