Three popular adventure movies. 'MirrorMask' (2005) was written by acclaimed comic book writer Neil Gaiman and directed by his frequent illustrator Dave McKean. The story follows Helena (Stephanie Leonidas), a 15-year-old girl whose parents are circus performers, and who wishes that she could run away from home to join the real world. When her mother (Gina McKee) falls ill, Helena is convinced that it's her fault. Slipping into a fantastical dream world, Helena has to search for the fabled MirrorMask so she can heal the White Queen (McKee), and heal her mother. But as Helena further explores this strange world of unusual creatures, she starts to question whether she is really dreaming at all. In 'Labyrinth' (1986), suburban girl Sarah (Jennifer Connelly) is forced to babysit her baby brother, and she wishes for goblins to take him away. When her wish comes true, the Goblin King (David Bowie) tells her she can rescue her brother only by negotiating the labyrinth that leads to the Goblin Castle. Finally, in 'The Dark Crystal' (1982), Jen (Jim Henson), the last of an elfin race, can only restore light to the world by retrieving the missing shard of the Dark Crystal. His quest is complicated by evil forces who want to use the crystal to destroy all life.
