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
Directed by: Michael Ritchie
Starring: Walter Matthau, Tatum O'Neal, Vic Morrow, Joyce Van Patten
Other mistake: After the 2 Yankees put ketchup on Lupus' head, Tanner sticks up for him. After the Yankees put Tanner in the garbage can, there's obviously more ketchup on his head from before, along with ketchup on his shirt that wasn't there before either.
Coach Morris Buttermaker: What if he tries something?
Amanda Whurlitzer: I'll handle it.
Coach Morris Buttermaker: Rolling Stones, 11 years old.
Amanda Whurlitzer: I know an 11-year-old girl who is already on the pill.
Coach Morris Buttermaker: Don't ever say that word again.
Amanda Whurlitzer: Jesus! Just who in the heck you think you are?
Coach Morris Buttermaker: The goddamned manager, that's who.
Amanda Whurlitzer: Big wow.
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.
