What's on · Max · US · September 18, 2026
Max’s September 1 movie dump is a horror aisle with one kids title hiding in it: Dr. Seuss’ Horton Hears a Who! The actually-new-for-kids stuff this month is Cartoon Network episodes — Krypto, Batwheels, Teen Titans Go. Ghibli and Harry Potter films are still the reason the kids profile exists.

Play tonight
Jim Carrey as Horton, the speck, ‘a person’s a person.’ The one family feature in Max’s enormous September 1 licensed drop. Kind, loud, no jump scares.
Watch for
New series
Preschool Superman’s dog. New batch this month.
New series
Tomorrow. Talking Bat-vehicles. Fine for 4–7.
New series
Gag cartoon. Harmless, exhausting, not a movie.
Already on
Totoro and Ponyo for little kids. Spirited Away and The Boy and the Heron for 10+ who can sit with grief. Max still has the US streaming deal.
Already on
The eight movies, not the HBO series (that’s Christmas 2026). Philosopher’s Stone / Sorcerer’s Stone is the family entry; the later films get darker.
Already on
236 episodes rated, 95% mild. Better weeknight than putting on Beetlejuice because it ‘looked cartoony.’
September 27
Tween spy cartoon. Milder than it looks.
Christmas 2026
Not out. Do not search for it in the app yet.
Catalog is US Max as of September 18, 2026. Titles move by country and can vanish without notice. Informal parent guidance — not an official ratings board. Your kids — your rules.
The films are already on Max. The new HBO series premieres Christmas 2026, not September.
PG, ghoulish, and a bad surprise for a six-year-old. Not on this list.
