This trailer was made to be reacted to
War trailers trade spectacle for weight, and the honest reactions are usually the quiet ones. Record yours anyway.
Every theatrical release wants the same thing: a real reaction before the reviews show up. Yours can be first.

Children Untold: quick answers
How do I make my own Children Untold reaction video?

Do I have to be on camera?
No. Voice Reaction mode records your commentary with the microphone only: the camera stays off, no face is recorded, and you still get a share-ready clip for your channel.

Children Untold is scheduled to open in US theaters on October 16, 2026. Dates can shift, so check back for updates.

Ami Koyae, Fumi Nikaido, Kaito Sakurai, Yutaka Takenouchi and Koji Yakusho lead the cast, directed by Miwa Nishikawa.
Is Reactr free?
Yes. Recording reaction clips on Reactr is free, with no paywall on the finished clip. You own your clip and can post it to TikTok, Reels, Shorts, or anywhere else. Reactr makes money from studios and sponsors, not from creators.
