I would recommend the first one the most
There's a character called Apollonia who's one of my favorites... I won't spoil it for you but let's just say she's a side character who has a HUGE impact on Al Pacino's character and the catalyst for him changing half way through the movie.
I watched that part of the Oscars and thought to myself, "Al and Robert and Francis are way too good for everyone else in here." Their appearance was a nice reminder of the past, of MEANINGFUL movies and great acting.
