Quote:
"Before winning an Academy Award as Best Documentary Short, the twenty-minute film [If You Love This Planet] was labeled as 'political propaganda' by the Reagan-era U.S. Department of Justice under the aegis of a 1930s era law. Copies of the film print shown in the United States were required to carry this warning label, creating a situation in which a documentary from the [National Film Board of Canada] was discussed as enemy propaganda."
