24 Year difference
Something I thought about recently! It's stated that Gina was 19 during the events of the movie when Tony says to her "You're gonna beat yourself to death at 19!?" And if Tony himself was the same age as Pacino at the time (early 40's) then that's a massive age gap between siblings. Cualquiera diria que es la hija! Just how young was mama Montana when she gave birth to Tony? And how old was she when she conceived Gina? Not to the mention the actress Miriam Colon was only four years older than Pacino in real life and didn't look that old to begin with! Was this an oversight by the filmmakers?
Not to mention, not to mention that the actress was Puerto Rican, not Cuban. But I digress!
