Mass culture was less stringently regulated than high culture, possibly because the authorities feared the consequences of too heavy-handed interference in popular entertainment. Thus, until the outbreak of the war, most Hollywood films could be screened, including "It Happened One Night", "San Francisco", and "Gone with the Wind". While performance of atonal music was banned, the prohibition of jazz was less strictly enforced. Benny Goodman and Django Reinhardt were popular, and leading English and American jazz bands continued to perform in major cities until the war; thereafter, dance bands officially played "swing" rather than the banned jazz.
