Jennifer Garner has a new alias: Box-office draw. The actress's first solo effort on the big screen, 13 Going on 30, opened at No. 2 over the weekend with a better-than-expected $22 million. The lighthearted comedy came in just a hair behind Denzel Washington's violent thriller Man on Fire, which snagged the No. 1 spot with $23 million. Kill Bill — Vol. 2, meanwhile, fell from first to third with $10.4 million — a steep 59-percent drop from its big debut last weekend.
