As mentioned a few months ago, Rob Marshall from Warner Bros/Disney is planning to make Stephen Sondheim's Into the Woods into a movie.

The screenplay reading  took place yesterday and included  Nina Arianda as The Baker's Wife; Christine Baranski as the Stepmother; Tammy Blanchard as Florinda; Victoria Clark as Cinderella's Mother/Giant; James Corden as the Baker; David Garrison as the Narrator; Ivan Hernandez as the Wolf; Megan Hilty as Lucinda; Cheyenne Jackson as Rapunzel's Prince; Allison Janney as Jack's Mother; Anna Kendrick as Cinderella; Michael McGrath as the Steward/Baker's Father; Donna Murphy as the Witch; Laura Osnes as Rapunzel; Taylor Trensch as Jack; Casey Whyland as Little Red Riding Hood and Patrick Wilson as Cinderella's Prince.

The cast for the film has not yet been announced, but rumour has it that Meryl Streep is in talks to play  the Witch, but was unable to make the reading yesterday.

James Lapine is reworking the script for the screenplay and Sondheim is expected to contribute some new songs.
