Greg Berlanti revealed he encountered the most limitations in the entertainment industry from people in the LGBTQ community.

Berlanti, who is openly gay, is the showrunner behind the hit shows “Riverdale” and “The Chilling Adventures of Sabrina,” which include queer characters. He also directed “Love, Simon,” the first mainstream teen romantic comedy to feature a lead gay male character.

In an interview with the Hollywood Reporter, Berlanti says it was hardest to cast gay actors in straight roles because of gay executives.

“Early on in my career there were gay execs and gay casting people who were the least likely to let me cast an actor they knew was gay in a straight part,” Berlanti told the Hollywood Reporter. “These were the individuals who knew how important it would be.”

Berlanti says he will believe Hollywood has changed to become more inclusive when, “The majority of rooms I walk into — executive suites or writers rooms or production floors — look and feel like the rest of America.”
