Jay's hopes for more movies like the 70's. I don't think that will happen because those types of drama movies if still getting made don't do well. Looking at the box office this year, it's $100 million crowd pleasers such as John Wick 4, Barbie, Mario Movie, Creed 3 and so on that are the hits, whereas movies like Fast X, MI7, and Little Mermaid aren't making a profit due to their huge $250+ budgets and that is before you go into outright flops like the Flash and IJ5.
I don't think blockbusters will go away but they will have to be made cheaper and smarter, the days when every blockbuster has a $200+ million budget are gone. It cost $287 million total for the back-to-back shoot of the Lord of the Rings movies, budget for the Hobbit movies was $700–745 million, while inflation can count for some of the higher budget, most of it is due to shit like unneeded CGI and other wastes of money because they knew it would be a hit based on the LotR movies and were lazier knowing that.
They also bring up the Irishman in the video, just want to say the budget of that looking online was anywhere between $159 million and $250 million, no shit Martin Scorsese can't get movies made with budgets like that without the help of streamers. Had Irishman or Killers of the Flower Moon ($200 million budget) had a budget closer to The Wolf of Wall Street which cost $100 million (which is already a bit high for that type of movie) no doubt he would still get deals with the big studios but at those budgets no way they will make money at cinemas.
