Walter's orphanage -- the only home he's ever known -- also needs funds desperately. Upon overhearing Walter's predicament, Eddie convinces the no-nonsense head nun, Sister Francesca (Malick), that Walter can win the money as a fighter and pay off the church's debts. Eddie's plan: travel from town to town with Walter and enter small, unsanctioned fighting competitions for prize money Sister Francesca dispatches Mary (Hardin) as a chaperone for both Walter and the money and gives Eddie a week - and a prayer - to make it happen. During their journey across the south to the annual Pro-Am MMA tournament in New Orleans, Walter discovers what life is like outside the orphanage, while Eddie becomes morally conflicted over whether to take all the loot for himself or keep his promise to Walter, the one person he can actually call a friend.

How to Watch Knucklehead Legally and Safely

If you want to stream Knucklehead through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry Knucklehead films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
