I don't like Cameron Diaz. But I always give her the benefit of the doubt which means sometimes I'm surprised. She's surprisingly great in In her Shoes, and serviceable in Knight and Day.
And I have some great news for you, Elizabeth. The fantastic original film IS available on DVD
from Universal's Vault series, where you can buy a DVD on demand.
A Coen Brothers script is great, but I still don't have much faith in Diaz. Especially with wordsmiths like the Coens. She's going to have to make an extra effort to just get the language sounding decent, let alone natural and light.
