If you download this PDF report from the Q2 2024 IMAX Investor Presentation, there are charts showing which films are being produced with IMAX in mind all the way through to the end of 2026.

It's interesting as it looks like a strong slate of blockbusters through the year, which might help the industry bounce back from this year. Unfortunately, it doesn't show the potentially more interesting (to me) films but that's fine, they'll be a nice surprise.

could its title be something other than Dune: Messiah?

He did adjust the story in Dune 2 to better align with Dune: Messiah but it also shows he is no respecter of the original stories, so he might still take things in a different direction, especially as Messiah is, in some ways a darker reaction to the success of Dune and it is unclear how well that would translate into a blockbuster movie. However, it may be Villeneuve has the confidence of the studios and will be given the room to make an... "anti-blockbuster".

I took the liberty of posting the IMAX release slate in a separate post.

So it looks like Denis is confident with completing the screenplay now, instead of making another film first.

I wish they never let that dude make the movies.... especially the 2nd one.... I felt like they given up on the whole movie, the second half felt like they ran out of time and ideas, so they made that anticlimactic boring ending. I coudn't even beleived my eyes..... The syfy miniseries in the early 2000s was way way waaaaaay better and enjoyable that this cashgrab. and let's make an other one? no thanks, I felt like the disaster they called "Foundation".
