"Our show is really different," the 22-year-old actor told ET's Katie Krause during a Facebook Live interview on Friday. Lynch is set to play Harvey Kinkle, the love interest to the eponymous Sabrina Spellman, played by Kiernan Shipka.
While Sabrina the Teenage Witch was based on the Archie Comics series of the same name, The Chilling Adventures of Sabrina is an adaptation of a much darker, more adult series from Archie Horror, an imprint of Archie Comics that caters to an adult audience with grittier tastes when it comes to their comics.
Originally, there were reportedly talks to create the series asa companion to Riverdale, but those intentions came to an end when Netflix picked up the show. That didn't keep Ross and some of his Sabrina co-stars from hanging with a few members of the Riverdale cast.
However, the star was quick to clarify that fans shouldn't read too much into that.
"There's no talks of a crossover right now, [and] I don't know if there ever would be one because the shows are on different networks," Lynch shared.
The former Disney star, who dyed his hair brown for the role, also dished on the audition process, before noting he hadn't met Shipka prior.
"I kind of like it that way... gives me a chance to fall in love with her character," he explained.
As for the wardrobe in the darker reboot?
"Everything is classic," he revealed.
While he's excited to be a part of the show, he admitted that he was hesitant to sign on originally, because of how many different projects he's currently undertaking -- including his new band The Driver Era, which he formed with brother Rocky Lynch, and the release of their debut song, "Preacher Man."
"There were certain reservations that I had to saying yes to this project obviously, because there was a lot of music going and "Preacher Man" is very exciting and a lot of people are reacting to it," he explained. "But I really believe in this project. I just had a good feeling about it."
"I'm happy to say that so far my expectations have been exceeded," he added. "Just the aesthetic of everything and the actors that were cast and Roberto... all the visions are coming together and they're effective."
As for their new single "Preacher Man," the brothers just released a music video for the track, and Rocky said the song and the video have gotten "the best reaction of anything we've released so far."
