Went to see this last night and enjoyed it. Even burst out laughing on one occasion... Guffaw-like.
The movie was - far out - that's the only way I can describe it. It was very out there, even for Terry Gilliam! You could see influence from Monty Python's Flying Circus all over the place. They worked the Heath Ledger/Colin Farrell/Jude Law/Johnny Depp thing extremely well. I don't want to ruin it for anyone else by going into too much detail. Amazing set design, utterly mental costumes and groovy special effects.
A very strange movie but I'm glad I saw it!
Here's the trailer - enjoy -
