But the director is the most impotent cast member in the film. So he/she has much more power to influence the final result of the movie. Great cast performance will not help to the movie if direction is simply bad.
Personally I would choose director first... as this is the head of the crew members and his impact is the most valuable.
And remember that *-rating is relative. It means that it
3* is base... which means that performance of given person is on expected level for his talent.
>3* means that performance above expectation and
<3* performance below possibilities given person.
(there are some extra bonuses for film in manners of points when all cast has >3*)
Hope it helps a bit with understanding of logic behind the game.
