I tried asking my friends from fb but I don't think I have enough movie buff friends to respond to it. I'm trying to look for the title of that movie, set in the not so distant future (so forget about the idea of robots or flying cars), when people's tombstones don't have epitaphs anymore but rather a video summary of their life's best moments playing on a mini screen. Movie came out sometime between 2003 and 2007. I don't remember any actors who played in it (it's one of those movies you wish had better marketing because it was good but not so known). I just know that the plot did revolve around this innovation of putting your life videos (taken from first person perspective of the person who died) on the tombstone instead of epitaphs written by your friends/family to summarise your life.
