Was this written by a non-native speaker? I guess native speakers would write "the stature of the filmmaker Kurosawa", but is this way also common and normal?
ex)...You must pay me," Kurosawa wrote. Leone, who was thrilled that a filmmaker of Kurosawa's stature would threaten to sue him, eventually agreed to give him fifteen percent of Fistful's worldwide box-office receipts.
I agree, and I can't see a way to make "the stature of the filmmaker Kurosawa" fit into that sentence without it sounding very unnatural indeed. You could at a pinch say "...who was thrilled that a filmmaker of the stature of Kurosawa would threaten to sue him..." but I think the original way is by far the most natural.
