Sky is the limit for me with right director: Alia Bhatt

In "Udta Punjab" - which Alia feels is "definitely the most difficult film" of her career -- she is seen as a Bihari immigrant trying to break away from the shackles of the drug menace in Punjab. As part of her role, she brings forward dreams of a Bihari hockey champion, who leaves her hometown in search of fame and success, and gets caught among drug peddlers.
