Grudge Match, an under-the-radar sports-comedy film featuring Sylvester Stallone and Robert De Niro, weirdly pays off a 33-year-old movie dream for viewers. Directed by Peter Segal (Tommy Boy), Grudge Match centers on two aging boxers, Henry “Razor” Sharp (Stallone) and Billy “The Kid” McDonnen (De Niro), who step into the ring for a final match-up. Back in their glory days, the Pittsburgh-based boxers became storied rivals after a couple of fights. Kid and Razor each lost one fight during their long careers to each other.
