“It: Welcome to Derry” is an upcoming Max (formerly HBO Max) original prequel series set in Stephen King’s IT universe, so it will stream exclusively on Max in regions where that service is available.

Where you’ll be able to watch

  • In the US, the show is expected to stream on Max, as it is being developed as a Max original series tied to the IT film franchise rights already held there.
  • In many international markets where Max does not operate yet, Warner Bros. series often appear via local partners (for example, on certain regional streamers or pay-TV channels), but exact international platforms for “Welcome to Derry” have not been fully detailed publicly yet.

Timing and availability notes

  • The series has been in development as a prequel focused on Derry and Pennywise’s earlier horrors, connected to the continuity of the recent IT movies.
  • Release window and regional roll‑outs can shift, so the safest approach is to search for “Welcome to Derry Max series” on your local Max app or your regional Warner Bros. partner closer to premiere.
