When i said that Wilde is like a supermodel, i didnt mean literally, but she's too thin, too tall and too gorgeous to be Lois. She's too perfect and stunning. She's not the next door girl that wins you over with her charm, whits and spunky personality like Lois is supposed to be.
Not that Lois isnt beautiful, but she's more of a working girl than THE beauty of the office that Wilde would be. Watch Morning Glory and see how McAdams keeps tripping, falling, talking too much, dropping things and running all over the place and coming off as a cute, sassy and very clever girl that's out there to kick butt and make it big. That's Lois.
When you ask the fellas at the office about Lois they should respond with "dont mess with her", or "she's got more balls than superman", "she's a lunatic" rather than "OMFG she's so hot, lets go to the photocopier to peek at her".
Can you seriously imagine Olivia Wilde making spelling errors and asking Smallville how to spell words? She's too perfect for that. Unless of course you re into some other version of Lois. I'm partial to the L&C, BTAS, Smallville one.
See this trailer. It shows a bit of what i'm talking about.
