Los Angeles ? Movie audiences accepted a proposal from Sandra Bullock and Ryan Reynolds, who scored the summer’s first big romantic comedy hit.

Bullock and Reynolds’ “The Proposal” took in $34.1 million to open as the weekend’s No. 1 movie, according to studio estimates Sunday. The Disney flick delivered the biggest opening ever for Bullock, nearly double that of her previous best of $17.6 million for the 2007 paranormal thriller “Premonition.”

Bullock stars as a ruthless publishing executive who coerces her put-upon assistant (Reynolds) into a fake marriage so she can avoid deportation back to her native Canada.

“The Proposal” took over the top spot from the Warner Bros. bachelor-party comedy “The Hangover,” which slipped to second place with $26.9 million. A surprise smash hit, “The Hangover” raised its total to $152.9 million.

Disney’s animated adventure “Up” was No. 3 with $21.3 million, lifting its total to $224.1 million and following Paramount’s “Star Trek” as the second movie of 2009 to cross the $200 million mark.
