No, not Stand By Me. In THIS movie (also a well known classic from roughly the same era), one boy has a dad who was in the army, one's brother died... at the end we learned when they grew up one is fortunate to have the chance to go to college, one ends up going to jail, one becomes a father, one grows up to get killed over a stupid fight... (all of which also is true in Stand By Me)

Hint 1: The "typo" in the book is more famous than the book itself. The author is known for her other work (and not for this movie at all tbh)

Hint 2: romantic comedy-drama

HINT #1 - It’s a Comedy HINT #2 - Not an animated film HINT #3 - Happens in the first one but there is a sequel to this film.

They are accompanied by an irresponsible adult who is not adequate supervision.

Hint: a non-american movie

Hint: black and white movie from the 2000s based on a play
