Good Family Movies on Prime Video Right Now (September 18, 2026)

Prime’s September 1 licensed drop is mostly thrillers. Buried in it: two Ice Age movies that actually work for a family couch. SpongeBob’s latest theatrical is on Paramount+, not included with Prime.

Updated September 18, 2026.

Newly added — start here

Play tonight

Ice Age (2002)

PG · Added September 1 · Best for 5–10

Manny, Sid, Diego, the baby. The saddest beat is a mother pushing her child to safety — short, not gory. Scrat is the whole joke. This is the one September Prime add that is actually a family movie.

Watch for

  • A parent’s death implied in the opening
  • Cartoon chases and a tiger reveal

Play tonight

Ice Age: Dawn of the Dinosaurs (2009)

PG · Added September 1 · Best for 6–11

The third film, dinosaurs underground. Bigger set pieces than the first. Still a kids adventure, not Jurassic Park.

Watch for

  • Dinosaur hunts and falls
  • A baby-dino subplot with mild peril

Already on — we rated these

On the service, not for family night

Coming later this month

September 23

The Love Hypothesis

Adult rom-com. Do not add it to the kids profile because it is ‘new.’

Catalog is US Prime Video 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.
