In 1987, Lucas produced Willow, and Howard directed the movie; which featured Warwick Davis as a would-be magician, Willow Ufgood.
Via Variety, Howard was a guest on the Happy Sad Confused podcast, and he said that a Willow sequel series was in “serious discussions” with Disney+ to make it happen.
Over three decades ago, Ron Howard teamed up with George Lucas on the fantasy film called Willow.
Presumably any Willow sequel series won’t be bound by any of the events of the Shadow War books.
