Goldie Hawn would be wrong for Salome Otterbourne Imelda Staunton would be would be better, but I agree the Cast-list has to have impressive names mixed with less well-known ones, Emma Thompson should play Miss Bowers, the Actresss often confused with Glenn close (I can't remember her name), Goldie Hawn or Shirley Macclaine could play Miss Van Schuler
This version needs big stars if it wants to match Murder on the Oreient Express' success. I think Goldie Hawn would be great as Salome Otterbourn. I know the character was UK in the book but Branagh shook up a few of the nationalities for Murder on the Orient Express. Chris Hemsworth for Simon Doyle, Claire Foy from the Crown for Jaqueline. Denzel Washington for the American lawyer. Jennifer Lawrence for Linnet. Helen Mirren for Mrs Van Schuyler. Emma Thompson for Miss Bowers (she would make a good Salome too).
