The movie is an adaptation of Lewis Caroll's novel Alice in Wonderland and Through the Looking Glass. I have been waiting for this movie because it's directed by the Famous Tim Burton. I'm a huge fan of his works. He always turn something natural to something phenomenal. I'm sure this movie will be a hit just because Tim Burton and Johnny Depp are working together. Correct me if I am wrong but as far as i know Tim Burton always hire Johnny Depp in his movies and together they have become a force to be reckoned  with when it comes to movies.

Below are some of Tim Burton's Works:
Edward Scissorhands
Batman Returns
The Nightmare Before Christmas
Ed Wood
Batman Forever
James and the Giant Peach
Mars Attacks!
Sleepy Hollow
Planet of the Apes
Big Fish
Charlie and the Chocolate Factory
Sweeney Todd: The Demon Barber of Fleet Street

Haha I know you are familiar with his works so that's one reason to be excited.
