Isla Fisher spent sleepless nights over first lead role

London, Feb 26 (ANI): Isla Fisher was so worried to play the lead in 'Confessions of a Shopaholic' that she would wake up in the middle of night to mentally prepare herself for filming.

It was for the first time that the 33-year-old actress was playing the protagonist in the big screen adaptation of Sophie Kinsella's books about Becky Bloomwood.

Isla plays a financial journalist who struggles to keep her shopping addiction under control.

And the actress was so scared with the responsibility that she found herself waking at the crack of dawn to mentally prepare for a day on-set.

"(I would wake up) between 4.30 and 5.30," The Daily Express quoted her as telling Moviehole.net.

She added: "I'd never been the lead in a movie before, obviously there's the fear that goes along with being responsible for the tone of the film, then there's the actual physical endurance side, and that was sort of like running a marathon." (ANI)
