Billy "The Kid" McDonnen (DeNiro) and Henry "Razor" Sharp (Stallone) are two local Retired fighters who have a famous rivalry, tied at 1-1. They are coaxed out of retirement for the decisive 3rd matchup by boxing promoter Dante Slate Jr., the son of their original promoter.
McDonnen reunites with his son and is trained by him. Sharp reunites with his ex Sally Rose (Kim Basinger) and is trained by la ong-time friend and trainer (Alan Arkin).
I enjoyed that this movie kept it real....they acknowledged the age and condition of both (Stallone is 67 and DeNiro is 70) and showed their difficulty even with training. They didn't try to ignore their age and pretend they are younger.
I won't spoil the ending, but I liked the way their match was handled.
A funny and entertaining movie.
