That first weekend, the biopic starring Jennifer Lopez rang up more than $11 million in box office receipts, making it the No. 2 film in the country. It had only been two years since singer Selena Quintanilla-Perez died of a gunshot wound, and her most dedicated fans in Texas lined up by the thousands to buy a ticket.
