One of my favourite love stories is Orhan Pamuk's Museum of Innocence. It's beautiful, isn't it?" says Lunchbox director Ritesh Batra over the phone from London. It's his love for love stories that may have propelled him towards his second film, The Sense of an Ending, adapted from Julian Barnes's novel of the same name. The story is about Tony Webster (played by Jim Broadbent), who goes back to his past and reflects on the paths he and his friends have taken. There is also a melancholic, unrequited love story in there.
