The latest additions to the Shrek the Third cast show that the film is not lacking a budget, and that Dreamworks have one amazing pool of story writing talent.

From Hollywood Reporter through Reuters come the latest casting updates. How big can this cast get?

The next instalment of the smelly ogre's saga, set for release next year, is set to star an elite, ninja-like strike force of fairy tale princesses voiced by Amy Sedaris as Cinderella, Amy Poehler as Snow White, Maya Rudolph as Rapunzel and Cheri Oteri as Sleeping Beauty.

Organized by Princess Fiona, the ladies underground resistance movement fends off a coup d'etat by Prince Charming (Rupert Everett) in the land of Far, Far Away.

That idea has come from a combination of some bizarre, warped and child-like minds, and I have to say I love it. Sounds superb. I think that this Shrek film might just be one of those films where the sequels get better and better.
