Sleeping Bride (ガラスの脳, Garasu no Nō, "Glass Brain") is a Japanese 2000 tragic-romance film directed by Hideo Nakata, based on a comic by Osamu Tezuka. It is probably best known to Western audiences for its inclusion in a Tartan Asia Extreme DVD release of the Ring trilogy, which included it as a fourth Nakata feature unrelated to the Ring series.
