It was a scene so chillingly accurate that nuclear experts praised director James Cameron for 'getting it right'.

The imagined sequence in Terminator 2: Judgement Day showed leading character Sarah Connor getting obliterated by an atomic bomb that had hit Los Angeles.

Now, Cameron is planning an 'intense' film about the 1945 nuclear attack on the Japanese city of Hiroshima that killed around 130,000 people 80 years ago, on August 6, 1945.

The production will be an adaptation of new book Ghosts of Hiroshima, which draws on 200 interviews with survivors of the blast, as well as those who escaped death in the subsequent attack on Nagasaki.

Speaking this week, Cameron told how the Terminator films - the first was released 1984 - were directly inspired by his experience of seeing a documentary about the Hiroshima blast when he was at college.
