A Great Insight into History,How Nuclear Bomb was made and its implications on World Order,Diplomacy, Rivalry between Nations,Society,Economy,Politics. Cillian Murphy as Dr Robert Oppenheimer is obviously same as his name. Robert Downey Jr as Lewis Strauss was great. Florence Pugh as Jean,Emily Blunt as Kitty and short but powerful impact role of Rami Malek as David Hill was Hard-hitting. Matt Damon as Leslie Groves,Alden Ehrenreich as Senate Aide,Jason Clarke as Roger Robb,Kenneth Branagh as Niels Bohr played their rolls well. Overall Christopher Nolan gave great direction to it and Music too was good along with Effects. Glad I watched it in IMAX Laser!
