Bomb at 10:10 has George Montgomery as an American flier in World War II in a Nazi prison camp in Yugoslavia who escapes with one other and is trying to make it back to the Adriatic coast and then Italy when he hears that the former camp commandant at his Stalag is now the governor of an area he's passing through. Montgomery decides to give him a little payback for the bad time he had as a prisoner.
Montgomery is the only name you will recognize in this cast of Yugoslav players. No doubt he did this one for the paycheck as Marshal Tito was opening up his country in the 60s to western film companies and trying to get a Yugoslavian film industry going.
When he makes contact with the Partisans it seems as though they have an unexploded bomb that Army Air Force dropped. They view it as the method to killing the commander in a Reinhard Heydrich type affair.
That together with a little romance between Montgomery and the commandant's daughter is what this silly film is about.
It is true that are Army Air Corps did do missions in the Balkans once we were established in Italy. But the only Americans on the ground were OSS people. One of them was Sterling Hayden who had he been caught would have been executed as a spy. Now his exploits in Yugoslavia might have made a great film, but of course he had his run-in with the House UnAmerican Activities Committee. Maybe one day he will be the subject of a film and I'm sure it will be a lot better than this one.
