Drew Barrymore's new whale rescue movie "Big Miracle" is a big flop, according to box office estimates.
 
The movie, based on a real-life story, brought in a lowly $8.5 million during its opening weekend - almost $14 million behind newly-released hits "The Woman in Black" and "Chronicle."
 
"Chronicle," which follows the exploits of a group of teenagers with superpowers, led the box office with $22 million and Harry Potter star Daniel Radcliffe's thriller "The Woman in Black" also had a big debut with $21 million to come in a close second.
