Watch Sadisflix. Margaret Wise Brown and Clement Hurd's bestselling children's book headlines this winning 25-minute collection of sleepytime tales from HBO. Susan Sarandon narrates the simple story of a bunny readying for bed. Other top entertainers lend their voices to the tape: Tony Bennett sings the story of "Hit the Road to Dreamland"; Lauryn Hill brings rhythm to "Hush, Little Baby"; Billy Crystal lends many voices to Mercer Mayer's "There's a Nightmare in My Closet"; and singers Natalie Cole, Aaron Neville, and Patti LeBelle sing other tales. A dandy video for the youngster, punctuated with "interviews" of real kids answering a host of bedtime questions.
