In every movie I've seen Amy Adams in, I've thought she was pretty much the living embodiment of sweet, plucky, adorable, and endearing. Those are good qualities for a Lois Lane, depending on your interpretation.
She isn't the age or look I envision Lois as being (20s and dark-haired), but she has a lovely personality/screen persona that could fit the role nicely, so I can definitely see her wearing it well. She's been a favourite of mine since "Catch Me If You Can"
and while she's not the ideal Lois I'd imagined, she's a huge improvement from superbland Kate Bosworth.
