Questions about Ontario Palace
- Does Regal Edwards Ontario Palace show Dune: Part Three in IMAX 70mm?
- Regal Edwards Ontario Palace is one of only 34 theaters in the US and Canada with an IMAX 70mm film projector, and Dune: Part Three is the film those projectors are running this December. Showtimes are sold by Regal; we watch them and tell you when seats open.
- The show I want at Ontario Palace is sold out. Can I still get in?
- Often, yes. People cancel, and a cancelled seat goes straight back onto the public seat map, most of them in the final hours before the show. That is the moment an alert is for.
- Does an alert reserve the seat for me?
- No. Nobody outside the theater can hold a seat. We tell you the seats opened, when we saw them, and where to book, and you book them yourself.
- What does it cost?
- Nothing during the Dune: Part Three run. Set a watch with an email address and no password.
