I know this sounds like a stupid question, but I always thought that the script breakdown (the list of all the elements needed for the movie, like sets, props, costumes, effects, etc.) was made by the director. But recently, I found out it was made by the producer, who sends it off directly to the department heads. But the thing is, I always thought it was the director's job to tell people what to do, not the producer's! Also, if the breakdown is set off from the producer directly to the department heads, how does the director tell the department heads how he wants stuff to look? I know that the director directs the editor and actors while they work, and that he makes storyboards and shot lists with/for the director of photography, but what about props/costumes and such in the breakdown (like I was just talking about)? Does he get sent the breakdown, and then either meets with them to discuss points or sends them descriptions or drawings with the breakdown? Also, if that is the case, how does the line producer know whether he's going to meet them in person, or just send them all drawings, or if he's going to make storyboards/shot lists with the DP or on his own and send them to the DP (for scheduling purposes). Speaking of which, who picks the cast and crew, the director or producer? And who decides whether or not the film will be shot on film or digital, the director or producer? And who buys all the stuff the departments need (for example, the DP needs cameras, the set people need material for sets, etc.)?
