There were reports (from sources I believe) that Williams wound up fairly frustrated with/exhausted by J.J. Abrams' modus operandi (revisions revisions revisions), so while this is not a surprise, it is nice that it's confirmed.
As for the fifth Indy movie, let's see if that actually happens.
Not gonna lie, I was losing interest in this until I saw the teaser. It's great to see the trio TOGETHER in action scenes, and it appears as if they are participating in the journey together and not fragmented, as in The Last Jedi. And of course the last part of the trailer totally made it worthwhile...
Fantastic to have Princess Leia’a Theme front and center driving the teaser. Also, best opening to a Star Wars trailer yet. Every time they release one of these things I feel like I’m 10 years old again watching the first one unspool. Great job!
