I have very early memories of two unrelated old films that I've never seen since and have always wondered what they were. The films must have been made in the 1950s or 60s and were shown on television around 1970.

The first is some kind of modern-day western where a man (cowboy/Mexican?) has to make a long journey on a horse but just as he's about to get there he's hit and killed by a car while crossing a road.

The other film is very vague but might be a World War 2 film. A man is camped in the jungle with a group of others but when he wakes up one morning they've all left and he is alone.

Any ideas on these?
