A controversial Michael Jackson documentary screening at the Sundance Film Festival has attracted protests.
A dozen Park City police were on hand at the premiere of the four-hour documentary Leaving Neverland, which details the 'Beat It' superstar's alleged child sexual abuse.
Capt Phil Kirk with Park City police says they have ramped up security in the area.
"We start identifying those films way in advance, and this is one of those that were identified," he said.
Two friends drove 13 hours, all the way from Canada, to encourage others to do their own research.
They argue the stars of the movie had their time in court, and now the late singer nor can his family cannot defend themselves.
"Anybody can make any number of videos, movies about him without any repercussion, just because it's not illegal to defame someone who's deceased," said Brenda Jenkyns.
One of the two men in the documentary testified under oath in 2005 Jackson never abused him. Jackson was ultimately acquitted of all the charges against him.
"The film takes uncorroborated allegations that supposedly happened 20 years ago and treats them as fact," his estate said in a statement.
"The two accusers testified under oath that these events never occurred. They have provided no independent evidence and absolutely no proof in support of their accusations, which means the entire film hinges solely on the word of two perjurers."
They accused the filmmakers of not seeking outside opinions and neglecting opposing facts, and said Leaving Neverland was a "rehash of dated and discredited allegations".
