Yes I too would like to see the rating higher as "Tryavna" above suggests such that I rated this film 7/10.I bought a job lot from a rare DVD dealer but somehow did not play this title until today.Being born in 1946 I can well remember building sites on which me and friends would play in our free time (very dangerous when I look back).England still had lots of bomb damage in 1957 and bomb site car parks were common.Us children traded objects out of school but I was never offered a real diamond!The afore-mentioned user has adequately commented on the plot and production values and I agree the film needed speeding up somewhat, although it kept my attention to the end.Of course the moral film code was much in evidence in 1957 so that any criminal caper had to show the perpetrators obtaining their just deserts in the end.
Belinda Lee. although mainly a glamour puss in British and continental films in the 1950s, here is given a real acting part which does not just trade on her outstanding physical looks as she has to play a friendly & sympathetic relationship with her young 14 year old co-star.It was sad her life had to end prematurely in a car accident in the USA in 1961.Curiously there was no film music heard in the chase scene on the building site between Lewis, Brookes & Lee.There has been a real life raid recently on a safe deposit in Hatton Garden,London which was in the papers and which makes this film quite topical.
