Grey's Anatomy/Trivia

Directed by Cast Member: Kevin McKidd and Chandra Wilson have both spent time behind the camera.
Executive Meddling: There were originally four core interns, but producers felt that another male intern should be added. Enter Alex, who had to be both digitally added the pilot and required new scenes to be filmed.

  - That's actually Sarah Hagan. So Devo was a Potential Slayer in a past life.
- Before joining the US army (and I mean a little over 2000 years before) Owen Hunt was a centurion of Caesar's 13th legion.
  - Not to mention if Seattle Grace is ever under werewolf attack, Hunt will save the day!
  - And apparently one of his former army buddies is Audrey Raines.

Promoted Fangirl: Camilla Luddington is excited to be playing Alex's Love Interest.
Reality Subtext: Early in the show, George is constantly asked whether he's gay. He's not, but his actor T.R. Knight is.
What Could Have Been:

- Sandra Oh (Cristina) had played Brooke Smith (Erica)'s lesbian lover in an unrelated production, and the two mentioned that they would be comfortable with their characters hooking up.
