Netflix has a movie regarding these two popes. It’s a pretty riveting movie to watch that gives some (hopefully historically accurate) account of why Francis became the natural successor to Benedict. It touched upon Francis’ history, his fall from faith and rebirth into who he is now. Sprinkled throughout the movie, the writers somehow managed inject dry humor into a fairly serious movie.
Interestingly enough, the two actor’s are nominated for best actor and supporting actor roles as well. I certainly hope one or both win.
