Gov. Jerry Brown today signed the measure which bars registered sex offenders from representing minors working in the entertainment industry. It also requires criminal background checks for managers, publicists, photographers and others with unsupervised access to young performers. The bill, AB1660, gained momentum last year after the arrest of a convicted child molester who had been working as a casting associate involving children in films. Authorities also determined Jason James Murphy had been employed on movies with children in their casts including J.J. Abrams’ Super 8. He was arrested on charges he violated state sex offender registry laws. A short time later, the Los Angeles Times reported that a manager representing young talent was arrested and subsequently convicted of felony child molestation. Until now, only agents and studio teachers have been subjected to fingerprinting and background checks.
