After Hollywood writers and producers refused to answer HUAC questions about their political beliefs, the following outcomes occurred:
-
They were blacklisted and barred from employment.
This was one of the most significant consequences. Many writers, directors, and actors who refused to cooperate with HUAC or were suspected of Communist affiliations found it extremely difficult, if not impossible, to find work in the industry due to being blacklisted. -
They were jailed for contempt.
Some individuals were indeed jailed for contempt of Congress for refusing to answer questions posed by HUAC regarding their political beliefs or associations.
The other options listed, such as Hollywood refusing to continue making movies until the investigations stopped, gaining widespread support from the American public, and having their First Amendment rights upheld through a lawsuit, did not occur as described. Hollywood industry response was complex and varied, and while some supported the blacklisted individuals, many others complied with HUAC to protect their own careers.
So, the correct options are:
- They were blacklisted and barred from employment.
- They were jailed for contempt.
