Apple was a little bit vague about its new streaming service, Apple TV+, during its presentation last month, but the company's latest series pickup has us thinking we need to sign up.

TV Guide has learned that the latest A-Lister to head to the streaming service is Academy Award winner Julianne Moore. She's teaming up with Stephen King and super-producer J.J. Abrams for a psychological horror series based on King's 2006 novel Lisey's Story.

The announcement marks Moore's first series regular role since her days on As the World Turns (Note: She did win an Emmy for starring in HBO's TV movie Game Change, in 2012). It is also worth nothing that King will be writing all eight episodes.
