Final answer:
The advantages of Orson Welles only entering the screening room include maintaining an unbiased perspective as the 'first audience member' and delegating detailed editing processes to specialized editors, allowing for artistic focus.
Step-by-step explanation:
The question relates to the advantages of Orson Welles, as a director, entering only the screening room and not participating in the cutting room. One advantage involves the director maintaining their role as the 'first audience member,' a concept defined by Peter Stein, which allows for an unbiased perspective on the film as a whole. By not being involved in the cutting room, Welles could see the film as the audience would, ensuring the final product's coherence and effectiveness from an outsider's viewpoint. Another advantage could be that by focusing on the screening room, Welles was able to delegate the detailed post-production processes to specialized editors, which could lead to a more polished final cut. This separation of duties ensures the director can concentrate on overall storytelling and artistic integrity while technical experts handle the intricate details of editing.
