The Region 4 version of this DVD misses out on;
Alice In Wonderland DVD Storybook
Alice In Wonderland Trivia Game
"Operation Wonderland" Featurette
"The Unbirthday Song" Sing-Along
"All In The Golden Afternoon" Sing-Along
Theatrical Trailer
Whilst nothing is absolutely compelling about the above extras, the sheer quantity of them would make the R1 version the version of choice.
