Final answer:
Hollywood often considers politically relevant movies as detrimental to box office success, yet studios sometimes produce political films, acknowledging their critical importance.
Step-by-step explanation:
The remark made in Hollywood that "politics is box office poison" refers to the idea that politically relevant movies usually struggle to achieve commercial success. This notion is supported by the financial disappointments of films that tackle U.S. military politics, for example, those that delve into the country's involvement in Iraq.
However, despite the perceived risk, both major studios and independent filmmakers continue to produce movies with political messages, believing in the importance of these narratives, and sometimes these films also achieve critical acclaim even if they don't make a significant impact at the box office.
