I checked the first 5 of these movies and they appear correct :

• Wicked has an upcoming theatrical re-release on June 4, 2025 in the United States
• Nosferatu will be released on May 16, 2025 in Japan
• Mission: Impossible will be released on May 23, 2025 in Vietnam
• Pride & Prejudice will be released on May 26, 2025 in Dominic Republic
• We Live in Time will be released on May 16, 2025 in Taiwan

The upcoming endpoint check all the release dates listed for each movie.

thanks for the reply, so if I'd like to get the first 20 upcoming movie in US, which original release date (mean no re-release or something similar) is bigger then today, how to do it? I'm pretty confused

You need to use discover

• either with check on the primary_release_date to only check the first release date
• or a region parameter and with check on the release_date to only check on all the dates in a specific region.

I'm not sure that you can combine the 2.

upcoming endpoint return film really old
Hi guys, thanks for your amazing work.
The endpoint upcoming is returning old data,
I know release date is different for each country, but i'm getting like film 50 years old, or 25 years old, or from the last year.
I leave a LINK to show to you the log (title is title|originaltitle and date is releasedate).
I know I could use the discover endpoint, but it's a bit more tricky.
Thanks.

I think you didn't specify the Region value.
Try this:

https://api.themoviedb.org/3/movie/upcoming?language=en-US&page=1&region=US  

This should eliminate movies released in other countries.
But it won't eliminate re-releases in your country, US.
To eliminate re-releases, just use Discover with the &with_release_type= filter.
I think with parameters 2,3
&with_release_type=2,3

*Movie Release Type* (with_release_type string)
ID  Release Type
1   Premiere
2   Theatrical (limited)
3   Theatrical
4   Digital
5   Physical
6   TV
