Bollywood director JP Dutta is back where he belongs: on the battlefield. The 68-year-old director’s new movie `Paltan` tackles India’s military operations against the Chinese army in Nathu La and Cho La in 1967. Dutta describes the September 7 release, whose cast includes Jackie Shroff, Arjun Rampal, Sonu Sood, Gurmeet Choudhary, Harshvardhan Rane and Siddhant Kapoor, as the concluding chapter in his war trilogy. `Border` (1997) and `LOC Kargil` (2003) revisited crucial episodes in India’s armed conflicts with Pakistan. Besides , `Refugee` (2000) marked the acting debut of both Abhishek Bachchan and Kareena Kapoor and examined border crossing between India and Pakistan.
