Animated tale based on the children's book 'The Old Man of Lochnagar' by H.R.H. The Prince of Wales. The story follows the quest of the Old Man, who lives in a cave by the Loch under the mountain, Lochnagar, to save the miniature green people of Gorm from the menacing Giant Gormless. His quest leads him under the sea, through the air and into Gorm Grotto and features a wealth of eccentric characters, including the Pig Eagle, a grumpy Grouse and Loch-Haggis, underwater haggis who revolve as they swim. This film stars H.R.H. Prince Charles himself in live action segments and also features the vocal talents of Robbie Coltrane as the Old Man, Chris Barrie and Hannah Gordon.
