Chills and thrills abound in Netflix’s offerings for October, with plenty of spooky content for Halloween. From Netflix’s buzzy adaptation of Daphne du Maurier’s 1938 gothic novel, Rebecca, which stars Lily James and Armie Hammer, to the family friendly original series The Worst Witch, there’s something to help everyone to get in the spirit of the season. David Letterman serves up wit and his signature wry humor when he returns for a third season of his Netflix original series My Guest Needs No Introduction on October 21.
