The Dam Busters is a British film about developing a new kind of round bomb to be dropped from low-flying planes. The bomb skips on the water until it hits a dam.
Von Ryan's Express is about escaping from a POW-camp in Italy, starring Frank Sinatra.

Dam Busters is so good! Also, next time you watch it, see how much George Lucas ripped off from that movie for his attack on the Death Star!
The whole “Red Five standing bye” communications part of the attack and many other aspects were completely lifted from Dam Busters.
