Trivia: Tin Man
- Ascended Fanboy: Zoey Deschanel was a huge fan of the original film and had wanted to play Dorothy for most of her life. She said that Dorothy had been her favourite character since she was two.
- Awesome, Dear Boy: Neal McDonough said that, after playing Buck Compton in Band of Brothers, this was his favourite role.
- Hey, It's That Guy!:
- Richard Dreyfuss as the wizard.
- Callum Keith Rennie as Zero.
GeneralM. Bison is Cain. You may also recognize him as Buck Compton or Robert Quarles.
- Tigatron (or "Flutterguy") is Tutor.
- Carmen Aguirre as the unnamed waitress in the opening scenes.
- Alan Cumming as Glitch/Ambrose
- Trick as a member of the Eastern Resistance Guild
- Retroactive Recognition: If you can see past the mustache and bowler hat, you might notice Cain is "Dum Dum" Dugan!
- Separated-at-Birth Casting: Zoey Deschanel and Kathleen Robertson certainly look like they could be sisters in real life. Likewise Rachel Pattee who plays DG as a child, has a striking resemblance to Deschanel.
- What Could Have Been: The story was originally going to have the Tin Man as the protagonist and be more about the police in the Emerald City, hence the title. It was then retooled into a re-imagining of the original story. The creators couldn't think of a better name, which is the reason for the Artifact Title.
