LOS ANGELES - The star-studded romance "Valentine's Day" wooed audiences with a $52.4 million opening weekend, easily grabbing the No. 1 spot over the holiday that shares its name, according to studio estimates Sunday. "To have a movie titled 'Valentine's Day' on Valentine's weekend was a no-brainer that absolutely worked," said Paul Dergarabedian, box-office analyst for Hollywood.com. Directed by Garry Marshall ("Pretty Woman"), "Valentine's Day" was a celebrity bonanza. The cast includes Ashton Kutcher, Jessica Alba, Jennifer Garner, Anne Hathaway, Julia Roberts, Jamie Foxx, Queen Latifah, Jennifer Biel, Shirley MacLaine, Taylor Swift and Taylor Lautner. "Valentine's Day" distributor Warner Bros. estimated its love story will be in the $60 million range after Presidents Day on Monday. That would break the Presidents Day weekend record of $52 million set by "Ghost Rider" over the four-day holiday weekend in 2007. Opening in a tight race for No. 2 were 20th Century Fox's action fantasy "Percy Jackson & the Olympians: The Lightning Thief" with $31.1 million over three days and Universal's werewolf tale "The Wolfman" with $30.6 million. Adapted from the opening book in Rick Riordan's fantasy series, "Percy Jackson" follows the adventures of a teen who learns he's descended from the ancient Greek gods. The cast includes Uma Thurman, Pierce Brosnan, Catherine Keener and Rosario Dawson.
