Can anyone help identify a movie?

I recall seeing a movie from the 70's or 80's where a man either kidnaps or somehow has a woman with him who doesn't wish to be with him. There's a scene where they are in the bush driving an old 4 wheel drive truck, and they end up getting stuck. The man manages to get the truck out by using a rope, and twisting it with a bar. At some point the two of them end up falling in the mud and wind up kissing each other. Does this sound familiar to anyone?

 

Romancing the Stone?

 

No. It was an older movie.
