My dad took me to see that film at the ABC Cinema in Southampton when my little brother was having his tonsils out. ..................... That must be something like 55 years ago
I just Googled it. The Film was made in 1954 so my guess was a year out.
I do remember my Dad saying how realistic the effects were in the film. "You can almost smell the smoke from the explosions" he said. When we got outside there were fire engines all round the cinema. Seems some arse had stuffed icecream wrappers into one of the air vents and set light to them. Dad died many years later but whenever asked what was the last time he went to the cinema ~ it was that film he had been to see.
