Long-on-the-shelf thriller 'Case 39' is the last thing Renee Zellweger needs to remind movie audiences that it's been quite a while since she hit one out of the park. The film took in a disappointing $5.4 million this weekend, even though a relationship between Zellweger and her co-star Bradley Cooper spiced up the tabloids. -- by Anne Thompson

Signature Line:
"You had me at hello." ('Jerry Maguire')

Career Peaks: In 1996, Zellweger played the lovable chipmunk-cheeked girl next door who wins the love of jacked-up talent agent Tom Cruise in 'Jerry Maguire.' Women also identified with her as a Jane Austen-inspired chubby Brit diarist in 'Bridget Jones Diary' and its sequel.

Awards Attention: 'Bridget Jones Diary'-and her flawless Brit accent garnered Zellweger an Oscar nomination, as did her showstopping turn as murderous song-and-dance girl Roxie Hart in the Oscar-winning 'Chicago.' Zellweger finally won for her folksy supporting role in 2003's 'Cold Mountain.'
