Sharing his experience of working with John Abraham in film 'Mumbai Saga', Rohit Roy said, "John has...great sense of humour, delivered poker-faced." "After working with Hrithik (Roshan) in Kaabil, I was sure I'd never find another co-star who's just as secure, but he and John are cut from the same cloth," he added. 'Mumbai Saga' is directed by Sanjay Gupta.
