No idea if it’s British, American, the actors or actresses. It sprang to mind when someone on the boards mentioned a film adaptation of Harry Flashman. It might be that adaptation, but I’m not too sure.

There are only two scenes I remember. In one, an Englishman and a German square up to fight, but while the Englishman takes off his jacket and gets his arms stuck, the German happily starts without him. In the second, said Englishman is trying to make an escape with a lady, along a dock or through a tunnel. An octopus attacks and starts slipping a tentacle up the woman’s skirt, which she seems to quite enjoy.

And that’s it. Any ideas?

Do any of these titles ring a bell?
