Director Vasan Bala has taken responsibility for the failure of 'Jigra', actress Alia Bhatt's lowest box office opener. "Alia could've been on any other film set, but Jigra, during that time...And she trusted me with that choice," Bala said while speaking with Fever FM. "So it is my responsibility to deliver box office...I need to analyse...Something has happened," he added.
