Searching three titles (tv, movies) from 50's to 00's.

Hello. I'm looking for two movies and one tv-movie/tv episode. I've lost the titles but not pictures. The first one is a french or english movie with two teenagers in England, after a storm, they meet pakistanis people but some are harrassed by hooligans. Fun fact : I've seen the name of Christian Vander in the page of the film. The second is an italian movie from 50's : my only memory is a picture with a guy and a girl lighting candles up in a church and wearing a beret. The third one is a tv-movie or a TV episode : the pitch is about a team which tries to stop a machine of mass destruction. It's about nuclear war, Mutual Assured Destruction, and they use an experimental device to search an old guy's memories, and this old guy explains about this machine. That's all. Thanks in advance.
