Diana Penty has signed up alongside John Abraham for a Bollywood film based on nuclear bomb tests conducted by India. The film is tentatively titled ‘Shantivaan’ and is a thriller which is based on real life events from 1998, when the Indian Army did nuclear tests in Pokhran, Rajasthan. After light hearted films like ‘Cocktail’ and ‘Happy Bhag Jayegi’, Diana is set to surprise the audience with this intense adventurous and action drama. The Bollywood actress has been reportedly cast even in Anand L Rai’s sequel to ‘Happy Bhag Jayegi’. For now, Diana is set to begin shooting with John for ‘Shantivaan’ by the end of this month. The film is directed by Abhishek Sharma.
