In Speed, Sandra had to ensure that a bus continued travelling at a high speed as any reduction of speed will have the bomb in the bus go off. However, Priyan has decided to set his film in a train from London to Glasgow.
The Khatta Meetha director has already secured permission to shoot in London's trains.
The film will have Manoj Bajpayee play an engineer who has to control the train's speed, Ajay Devgn as a terrorist who plants the bomb, Kangna Ranaut as Ajay's love interest, Tusshar Kapoor, Sameera Reddy and a special appearance by Priyan's close friend Sunil Shetty.
