Labyrinth was directed by Jim Henson of the Muppet and The Dark Crystal fame. It was produced by George Lucas and featured David Bowie as the villain Goblin King. It's also one of Jennifer Connelly's first films. And it just might be the best live-action Alice in Wonderland film ever made.
Sarah (Connelly) is a proud cloudcuckoolander, someone whose head is permanently stuck in the clouds and who can very easily lose entire days playing make-belief in the parks. And then she's given the unenviable task of looking after her baby brother while her parents go out on a date. And of course the kid gets kidnapped by goblins within fifteen minutes. Top notch job there, Sarah.
To Sarah's credit, she's obviously distraught by this and does everything she can to get her brother back. Nevertheless, her character is a bit tough to get behind most of the time. You can see that her heart is in the right place, but otherwise she's a brat. Not helping the matter is Connelly's acting. It's atrocious, especially in the early scenes. As the movie progresses, she does get better, but she's not going to be winning any Oscars anytime soon. (Which is ironic because fifteen years later she did just that with her role in A Beautiful Mind.)
But, putting that aside, the film is otherwise a whole lot of fun. David Bowie is an absolute blast, although the songs he's given to sing could have been better. Jim Henson's puppet work is also on full display and is easily the best part of the film. Furthermore, the story has that mad, no logic whatsoever dream quality to it, which makes it enjoyable to watch, and the characters aside from Sarah are very enjoyable.
Not the best film ever made and I'd personally rather watch The Dark Crystal again, but if you've liked Henson's other films, this one is worth a watch.
