Answer:
the Hollywood Ten refused to answer HUAC's questions and blacklisted in the industry for years. 
Explanation:
At the investigation carried out by members of Hollywood Un-American Activities Committee, HUAC, many personalities and professionals  associated with  Hollywood  were asked about their associations with the Communist Party. While many cooperated with the committee, there were particular 10 individuals, who would later known as Hollywood Ten, refused to cooperate with the committee and denounced the HUAC anti-communist hearings as an outrageous violation of their civil rights.
However, this led to them being cited for contempt of Congress, where by they faced trial on that charge in April 1948, and each man was found guilty and sentenced to spend a year in prison and pay a $1,000 fine.
As the investigation went on, the Hollywood industry blacklist grew larger as Congress continued its investigations into the 1950s, until the 1960s when the blacklist ended.
Hence, as a result of HUAC's probe of alleged Communist influence in the film industry: the Hollywood Ten refused to answer HUAC's questions and blacklisted in the industry for years.
