Bombsight Stolen

A cranky scientist is working on a new bomber sight for use against the Nazis. He's holed up in a cottage in Scotland so he can work in private.

However, the place turns into a bit of a circus, with more and more people turning up. Clearly, the Germans are after his invention. But who is the bad guy? The weird new lodger? The butler? The wounded pilot? The cook? And who is the GOOD guy, trying to foil the Nazi plot?

This is a light thriller, with some fine actors (Mills, Sim, and a teen-aged George Cole in his first role) and some good plot twists. But because of the vein of humor throughout, it's hard to get emotionally involved even when the good guys are in peril. There are some scenes reminiscent of Hitchcock (the auction, the barn scene, the hall of mirrors), but in his hands, they would have been truly tense.

This is definitely worth a watch, if you are a fan of British films of the WW2 era, or if you enjoy Alastair Sim as much as I do. But all considered, it's a thriller without much of a thrill.
