I'm sure there are still some stubborn old directors shooting movies on film but aren't most shot digitally today? And even those shot on film are surely immediately scanned so post processing can be done digitally? Can't imagine anyone is still sitting with razor blades and splicing tape putting scenes together.
Films are mostly post processed digitally - but some, like Oppenheimer, are color graded the old optical way. While Dune was shot digitally, printed on film, then scanned back in again!
