Trailer for Abhishek Chaubey's 'Udta Punjab' is out and it looks promising! With the story revolving around the state's rising drugs issue, actors include Shahid Kapoor, Kareena Kapoor, Diljit Dosanjh and Alia Bhatt. While the trailer was much loved by the people, Alia's character as a Bihari wasn't received too well and the actress was criticised for stereotyping Biharis. While the issue is open to debate, the 23 year old sent a tweet out in response. She posted a picture that said 'hmmm' with a caption that read, “For every action, there is equal and opposite reaction plus a social media over reaction.” That is saying a lot with nothing at all, isn't it?
