Don 2 (also known as Don: The King Is Back) is a 2011 Indian action thriller film co-written and directed by Farhan Akhtar. It is the second installment of the Don series. The film was produced by Excel and Red Chillies Entertainment. The film stars Shah Rukh Khan, Priyanka Chopra, Lara Dutta, Om Puri, Boman Irani and Kunal Kapoor. A sequel to Don (2006), the film picks up five years after the previous film: The titular character, now the leader of the Asian underworld, plans to take over the European drug cartel. Meanwhile, Roma has joined the Interpol with a mission to hunt him down. After the success of the first film, a sequel was immediately planned. However, several delays including the selection of the right script, caused the film to be pushed ahead. The film was officially announced in early 2010, with filming scheduled to begin in later that year. Two fans of the previous film, Ameet Mehta and Amrish Shah approached Akhtar with a storyline and later they co-wrote the film with him. Principal photography took place in Berlin, where it was shot extensively. Shankar–Ehsaan–Loy returned to compose the soundtrack of the film, with Javed Akhtar penning the lyrics.
