It takes a bit of work to separate actual screenwriters from plain old writers (ie of source material). Setting my cutoff at 4 films.

1. Kôgo Noda 9.29 / 7 films (all for Ozu)
2. Ryuzo Kikushima 8.17 / 6 films (top film is by Naruse; other 5 all Kurosawa)
3. Shinobu Hashimoto 7.86 / 7 films (mostly Kurosawa)
4/5. Ennio Flaiano, Tullio Pinelli 7.75 / 4 films (same 4 films, all Fellini)
6. Ben Hecht 7.5 / 4 films (Hitchcock x 2, Hawks, De Palma)
7. Hideo Oguni 7.4 / 4 films (all Kurosawa again)
8. Bob Baker 7.25 / 4 films (Wallace & Gromit )
9. Tonino Guerra 6.5 / 4 films (mostly Antonioni)
10 Dan O'Bannon 5.75 /4 films ("Alien" movies + Total Recall)


Honourable mention to William Shakespeare (9.00 / 4 films but obviously not writing for film).
