Character mistake: After Loopis makes that bumbling bad play in right field that costs the Bears a game, in the dugout Tanner harasses Loopis and says "we would have won if it weren't for you." This statement is incorrect because the score was tied 0-0 in the last inning when Loopis made that bad play to make them lose 1-0... so although the Bears may have had a chance to win if extra innings were played and this play DID make them lose, a "win" wasn't guaranteed the way Tanner came out saying it.
The Bad News Bears (1976)
1 character mistake - chronological order
Directed by: Michael Ritchie
Starring: Walter Matthau, Tatum O'Neal, Vic Morrow, Joyce Van Patten
Continuity mistake: In the last inning of the championship game, Buttermaker opens a beer in a short brown bottle (perhaps a Pabst Blue Ribbon, Red White and Blue, or Red Stripe) right before Amanda grounds out. When he exits the dugout following the at-bat, he's holding a Coors.
Coach Morris Buttermaker: This quitting thing, it's a hard habit to break once you start.
Trivia: After this movie was released, the character Engleberg had to be recast because the actor who played him lost a lot of weight and no longer could play the "fat" catcher so a new heavy actor replaced him in the next two sequels.

Chosen answer: That red headed kid is Regi Tower, played by now-screenwriter and director Scott Firestone. Several of the boys had very minor roles, so Regi wasn't really an exception. His character did not appear in either of the sequels to The Bad News Bears.
