Natalie Wood and Christopher Walken in Brainstorm. It´s my favorite scene from the movie.

Movie plot:
Brilliant researchers Lillian Reynolds and Michael Brace have developed a system of recording and playing back actual experiences of people. Once the capability of tapping into "higher brain functions" is added in, and you can literally jump into someone else's head and play back recordings of what he or she was thinking, feeling, seeing, etc., at the time of the recording, the applications for the project quickly spiral out of control.

If I remember correctly, Michael Brace, Christopher's character and his wife Karen's marriage is on the rocks. So Michael decides to record his memories of the times they shared together, and the love they felt for each other when their relationship was still good. In this scene he brings the tape home for her to experience. Since she can feel, hear, smell, and see everything he does, well you can probably guess how this one turns out. :)

Man I can tell you, there's a time or two when a contraption like this would have come in handy in my life.
