Brian Peck, the former dialogue coach who pleaded no contest to sexually abusing former Nickelodeon starDrake Bell, had a signed self-portrait painting of infamous serial killerJohn Wayne Gacythat he flaunted in front of another child star.

In an exclusive clip shared with PEOPLE, formerAll Thatcast member Kyle Sullivan, then 14, talks about seeing the inside of Peck’s home, which included a shrine toPlanet of the Apesand — most notably — a painting of a clown holding balloons, which seemingly had nothing to do with the famous sci-fi franchise.

Sullivan says when he asked Peck about the painting, the dialogue coach became excited.

“Brian flipped the thing around and on the back it said ‘To Brian, I hope you enjoy the painting. Best wishes, your friend, John Wayne Gacy,’” Sullivan recalls in the clip.

“Brian actually developed a pen pal relationship with John,” Sullivan says. “He kept this pile of letters and photos from John Wayne Gacy in his nightstand next to his bed.”

“When we uncovered this revelation during the process of making the documentary, we were shocked," said series directors Mary Robertson and Emma Schwartz. “It raised a lot of questions about power dynamics on set and off, and what dangers were hiding in plain sight. Exploring those dynamic and revealing the secrets behind how culture is made is at the core of what we are trying to do withQuiet on Set.”

Bell, who is featured prominently inQuiet on Set,says Peck, whom he met on the set ofThe Amanda Show,became his manager after originally working with him as a dialogue coach.

The formerDrake & Joshstar says Peck sexually assaulted him multiple times, beginning when he was 15 years old.

“You know anytime I had an audition or anytime I needed to work on dialogue or anything, I somehow ended up back at Brian’s house,” Bell says inQuiet on Set. “And it just got worse, and worse, and worse, and worse, and I was just trapped. I had no way out. The abuse was extensive and it got pretty brutal.”

Peck pleaded no contest in 2004 to oral copulation with a minor under 16 and performing a lewd act with a 14- or 15-year-old, in connection with Bell’s case. He was mandated to register as a sex offender after serving 16 months in prison.

In 2021, Bellpleaded guilty toattempted endangering children and disseminating matter harmful to juveniles after an online interaction with an underaged fan. He was sentenced to two years probation and community service.
