One of mine is, It Happens Every Spring. Play ball! https://aurorasginjoint.com/2014/04/04/it-happens-every-spring-1949/
In no order whatsoever: Brian's Song, For Love of the Game, Bull Durham, Slap Shot, Major League, Murderball, Rocky / Rocky Balboa / Creed, The Natural, The Wrestler, Ford v Ferrari, The Hustler and, since e-sports are a thing, I'll cheat and toss in The King of Kong. The king of them all, of course, is The Sandlot.
Rudy is one of my favorite movies period. I could probably do Major League line for line. And I suppose Mighty Ducks if only because I worked as a goal judge at the arena it was filmed.
They just had the 25th anniversary of the movie like a month ago. This is low key one of my favorite films of all time.
Another of my favorites is Eight Men Out. And by the by, for you fellow baseball nerds... https://sabr.org/eight-myths-out
If I'm feeling like paying tribute to a more dangerous age and the warriors that survived it I turn to this.. But if I'm feeling like sitting in my pants drinking beer and eating cheesy Wotsits then it's this...
