It’s common to find that one’s DVD has a commentary on the film made by the cast, Director etc.
Today’s invention is an upgrade of that process for complex movies and on behalf of those of us who sometimes struggle to understand nuances in the plot.
The movie would be shown on a touchscreen, so that a viewer could click on a particular character and have a thought bubble appear.
This would state, without plot spoilers, who the person was, what they were currently doing and why.
This would also allow the Directors of films to indulge in very complex storytelling, without having to dumb-down their vision because they suspected that it would be just too hard to follow.
