The Montreal World Film Festival has canceled plans to screen the premiere of a new Hollywood film based on the horrific killings perpetrated by Canadian serial killers Karla Homolka and Paul Bernardo after half a dozen sponsors threatened to pull their funding. Lawyers representing the families of some of Homolka and Bernardo’s victims had previously tried to stop the screening by invoking Canada’s child pornography laws, but in the end, it was good old-fashioned capitalism that forced the festival to bow to pressure brought by the people writing the checks.
