Dateline Diamonds (1965)

I'm not sure if the Chantelles, Kiki Dee and the Small Faces had the same record company, but you could easily be forgiven for thinking so as they feature substantially amongst this otherwise rather poor diamond heist caper with William Lucas as "Maj. Fairclough" who ropes the heavily indebted Kenneth Cope ("Benson") who manages the Small Faces, into a diamond smuggling racket using the famous "Big L" pirate radio ship as their conduit to Rotterdam. The performances - especially an early one from Kiki Dee are all this has going for it - and that's not really saying much. The sheer silliness of the last half hour as the police close in on their safecracker tests even the most enthusiastic supporter of serendipity in a police investigation. If you are a fan of 1960s pop culture, then it might just be worth watching but otherwise...
