Meanwhile, Alia and Shah Rukh's film opened to mixed reviews. Dear Zindagi has recently been accused of being copied from TV show Being Erica, which aired on CBC in 2009. Director Gauri Shinde strictly denied the allegations and said: "Dear Zindagi is a deeply personal film. There is only one thing it borrows from, that's my life. There are a million films and serials with therapists like there are with doctors. Just because there is a doctor in a film does not mean it borrows from another film with a doctor." Being Erica also tracked the story of a young woman and a psychiatrist.
Dear Zindagi is Alia Bhatt and Shah Rukh Khan's first film together. The slice-of-life film also stars Ira Dubey, Angad Bedi, Kunal Kapoor and Ali Zafar.
