Although the hitRyan Murphy-helmed series went off the air in 2015, it remains a highly-discussed topic, andThe Price of Gleeis hoping to shed a new light onto the conversation.

“With unbiased filters, hear directly from those outside of the cast bubble who can provide no-strings-attached perspectives, such as: relatives and friends ofGleecast members; those who were on the set and close to it, such as set decorators, hairdressers, stylists and publicists; and entertainment reporters who covered the phenomenon,” states the series' description.

“I don’t want to say the C word — the ‘curse’ word — but that’s where your mind goes,” says one person in the trailer.

“My first reaction is blame. I still feel that there is someone to blame,” says another interviewee.

Other parts of the trailer see those who were close to theGleecast admitting, “You find out that somebody you know is not necessarily who you thought they were.”

“I can’t imagine what it must’ve been like to be that alone and end your life,” adds another person, referencing Salling’s death.

Rivera’s father George is also featured on the series, as he candidly reveals in an interview, “I knew that was the top of the mountain for Naya, for your kid, it was just surreal.”

At another point, he adds, “Fame can be poisonous.”
