If this were made in the 50s when it was set..
(though the book is in the present)
I'd cast
Character, (actual actor in movie), actor in 50s version in my scenario
Vienne (Juliette Binoache) Julie Andrews, which would make it pre-Poppins as a film debut.
Count or Conte or whomever (Alfed Molina) Billy De Wolfe, whose prissy mannerisms and fey fussin g would have done this role well.
The boy's mother (Carrie-Anne Moss) Leslie Caron, who DOES actually appear in the film briefly.
his grandmother and her mother (Dame Judi Dench) Zsa Zsa Gabor!!
Roux the River Rat (Johnny Depp) DEAN MARTIN!!! Good ol' Dino..
"And that's SHOWBIZ--kid."-Roxie Hart.
PROFILE PIC:Courtney Thorne-Smith.
MAGIC=Sarah Silverman.
