Netflix did not chill on Sunday. Instead, we got several updates on new series announcements, and anticipated arrival premiere dates, from the TCA summer press tour.

Get yourself prepared for a "Superbad" reunion on September 21. That's when the 10-episode limited series "Maniac" premieres, starring Emma Stone and Jonah Hill, with backup from Justin Theroux and Sally Field. The entire series was directed by Cary Fukunaga.

"Maniac" follows Annie Landsberg and Owen Milgrim, "two strangers drawn to the late stages of a mysterious pharmaceutical trial, each for their own reasons. Annie’s disaffected and aimless, fixated on broken relationships with her mother and her sister; Owen, the fifth son of wealthy New York industrialists, has struggled his whole life with a disputed diagnosis of schizophrenia."

Netflix broke out its own witchy lineup of Sabrinas to reveal the October 26 premiere date for this "Riverdale" spinoff series:

Kiernan Shipka has the lead role in this much darker take on Sabrina the Teenage Witch. The rest of the cast includes Miranda Otto, Lucy Davis, Ross Lynch, Michelle Gomez, Chance Perdomo, Jaz Sinclair, Richard Coyle, Tati Gabrielle, Adeline Rudolph, Abigail Cowen, Lachlan Watson, and even Bronson Pinchot.

Netflix just announced it has picked up this series executive produced by Octavia Spencer and LeBron James -- yes! Oscar winner Spencer will star in the eight-episode series, based on the book "On Our Own Ground," telling the story of entrepreneur Madam C.J. Walker, America's first black self-made female millionaire. The series is meant to be a "highly irreverent" look at the turn-of-the-century black-beauty-and-hair-care mogul's success, with Walker overcoming "epic rivalries, tumultuous marriages and some trifling family."

Netflix also announced it ordered the mystery drama series "White Lines" from the producers of "The Crown" and "Money Heist." In the series, "when the body of a legendary Manchester DJ is discovered 20 years after his mysterious disappearance from Ibiza, his sister returns to the beautiful Spanish island to find out what happened. Her investigation will lead her through a thrilling world of dance music, super yachts, lies and cover-ups, forcing her to confront the darker sides of her own character in a place where people live life on the edge."
