<<All of the "good" directors
are already taken (i.e. John Ford, Hitchcock, John Houston, Frank Capra,
Cecile
 B. Demille, etc.)>>
 
How about Billy Wilder? William Wyler? Michael Powell? Ernst Lubitsch?
Not all the good directors have been taken. Its just the trendy, publicized
directors which have been taken. Use your imagination. Take some chances.
