The FBI is monitoring threatening online posts revolving around Joker, which opens to the public Thursday night.

The agency has been notified of numerous threats tied to the film, but, so far, none have been considered credible, sources told The Hollywood Reporter.

"While our standard practice is to not comment on specific intelligence products, the FBI is in touch with our law enforcement and private sector partners about the online posts," the bureau told THR in a statement. "As always, we encourage the public to remain vigilant and to promptly report suspicious activity to law enforcement."
