Besson's

She's pushing cops to one side and it seems like Lucy is doing the same to rival films.<br/> <br />That's because Luc Besson's new movie has debuted at the top of the Chinese box office and knocked "Guardians of the Galaxy" into second place, taking more than 20 million dollars on its opening weekend.<br/> <br />It stars Scarlett Johansson as a woman who takes a drug that gives her incredible mental powers.<br/> <br />So far it's taken in 434 million dollars worldwide - a huge profit considering it was only made for 40 million dollars.<br/> <br />But it's still got some way to go before it catches "Guardians of the Galaxy".<br/> <br />The Marvel movie about extraterrestial misfits has grabbed 750million dollars at the box office.
