India, June 17 -- Actors Pankaj Tripathi and Janhvi Kapoor recently shot in Lucknow, Uttar Pradesh, for their upcoming film, a biopic on the IAF pilot Gunjan Saxena. Janhvi will be stepping into Gunjan's shoes to portray her character on screen, while Pankaj takes the role of her father, Anuj, in the film. Both Pankaj and Janhvi share a good rapport and have developed a great bond while working on the sets. The duo playing father and daughter on-screen were able to strike the chord before they even started shooting for the film. "They are spending a great deal of time prepping together. Janhvi would often drop by spending time at Pankaj's home to rehearse her lines with him. They both prep for their characters together, late into the night, over dinner. Sometimes, they are accompanied by the actor's wife Mridula, who's been the perfect host to Janhvi. Pankaj comes from a modest family background; whereas Janhvi comes from a family where three generations have been working in the film industry. They both listened to each other's life struggles and that became a source of inspiration for them," says a source....
