From wiki:
In October 2020, Brian Helgeland confirmed that a sequel to L.A. Confidential had been in active development before the death of Chadwick Boseman, who would have played "this young cop named James Muncie". Crowe and Pearce would have reprised their roles, and the film was to have been set in 1974.[8]

I’d like to see that.

Well that was foolish. It’s the perfect time to make a sequel to this modern classic. Crowe and Pearce have had their hey-days and wouldn’t be too expensive to hire. It would pretty much sell itself based on how well regarded the original is.
shareSo, basically, this is a way to make a 'diverse' movie and steal from the success of LA Confidential, since this would have almost nothing to do with the film LA Confidential.

Reports recently emerged that there was due to be an L.A. Confidential sequel in the works with yourself, Russell Crowe, and Chadwick Boseman. Did you know anything about that project and how it followed on from the original?share
-We started having discussions with [L.A. Confidential director and co-writer] Curtis Hanson and with James Ellroy some years ago now about whether we could do some sort of follow-up.
In the trilogy of books, that story is followed up. There was talk about whether we’d create something new, basically ten years on. 1963. It never went anywhere. It was just proving to be too expensive or too difficult.
I’m not sure what the Chadwick Boseman connection was. His name was never brought up to me at the time. But there were some rumblings in the camp which went away.
It’s unfortunate. I was excited at the prospect that we could revisit these characters one day.
