Even after 15 seasons and more than 300 episodes, there's still so much to uncover about . Beyond the show's weekly drama (and gut-wrenching heartbreak), there are tons of well-kept secrets about the cast, props, and set. Well, until now.
Grey's Anatomy creator Shonda Rhimes' inspiration came from her love of the medical shows she watched on the Discovery Channel. "My sisters and I would call each other up and talk about operations we'd seen," she said in an interview with . "There's something fascinating about the medical world — you see things you'd never imagine, like the fact that doctors talk about their boyfriends or their day while they're cutting somebody open."
"My show is more personal [than E.R.]. The idea for the series began when a doctor told me it was incredibly hard to shave her legs in the hospital shower," Rhimes told . "At first that seemed like a silly detail. But then I thought about the fact that it was the only time and place this woman might have to shave her legs."
Rhimes originally wanted to set Grey's Anatomy in her hometown of , but worried that doing so would make the show too similar to E.R., which was already set in there.
It was originally called .
You may have assumed it's a set, but it's a real house in . Yep, someone actually lives there.
"It didn't work out, and it went exactly the way it was supposed to go. Four days later, I get a call after I was passed over from Shonda saying, 'I really wanted you in this piece so would you be interested in playing a recurring character," the actor who played Dr. Preston Burke says of his initial audition.
Justin Chambers was brought on after the pilot episode. "The role of Dr. Karev ... they shot the pilot before I came on," . "The character wasn't even created yet, I don't think. They sent the pilot to New York where I lived and I saw it and loved it and I went out to L.A. to try to win the part and auditioned and got the role. So that's how Alex came about."
"Thank god I did not get that part," she joked at .
"At that time I was practicing asking for what I wanted in my life, which I still practice today. And I saw the part of Christina Yang and I wanted to do that part," she . "So even though Shonda wanted me to come in for the part of Bailey, I said, 'No I want to come in for Christina.'"
Shonda Rhimes and ABC network simply gave Pompeo the part. "I didn't audition for Meredith Grey; I was offered the part by Shonda and the network. Shonda Rhimes wasn't really 'Shonda Rhimes' at the time. It wasn't a big deal — it was just another pilot," she . "My agent said, 'Just do the pilot and make some money — these things never go.'" And here we are fifteen years later...
"I chose interns over established surgeons because I thought there's something really horrible about not knowing what you're doing for a living," she .
"I wasn't really trying to pull together any specific combination of characters together when I was picking the cast," she . "Whoever was best, that's who we were going to cast."
Chandra Wilson, Dr. Bailey was originally imagined as "a short, white, blonde female." Shonda that Bailey was, "the only character who had a description."
"I wasn't seen for it for awhile and then finally casting in New York saw me because she'd known me for years and said, 'Why not,'" Wilson .
But there was a bigger plan all along: "Honestly the reason we were so reticent about talking to her after she auditioned in L.A. was because she was perfect," . "We thought if we spoke to her we would all convey, 'Oh my god please we want you,' as opposed to letting things happen the way they're supposed to."
"You really don't know what's going to happen from day to day most of the time," said . "Stuff is always being rewritten and changed and storylines are being revealed to you. You really have to think on your feet. I didn't know I was married until halfway through."
"They didn't tell me that was coming," Pompeo . "I was very surprised."
"We have a really terrific medical producer, Linda Klein, who stages these operations and brings in real surgeons so the handwork you see a lot of the time is a real surgeon tying a knot," Executive Producer Jim Parriott .
Well, they come from (mostly).
"Initially it was just probably going to be a few episodes ... come in like a badass from New York and that'll be that," Kate Walsh .
"So I got into the room and [pilot director] Peter [Horton]'s very warm, very loving towards me ... we reconnect," he . "And then Shonda Rhimes looks at me. No expression, just looks at me. The entire meeting, just looking at me. No expression, no warmth, nothing. Everybody else is talking, it's very quiet, and then I leave. I call my agent and I'm like, 'It's not going to work at all. Shonda Rhimes hates me.' I was completely terrified; she's scary."
"The writers incorporate a lot of our own personalities into the characters. I cook, I bake, I knit. Izzie's the super moral version of me," Heigl .
"His wife Jill is very, very nice and very understanding, as is my boyfriend (now husband) Chris," she . "So we're completely guilt-free."
"I think one of the best-kept secrets of our show is that Justin has five kids and has been married for 10 years," Heigl told .
"This pretty blonde will read a book a day on set. I'm not kidding you, a book a day," Chambers told .
"T.R. keeps us all laughing, just continually," Heigl. "He's got the best sense of humor on set."
"One of my best, best-kept secrets is that I continue to train with real doctors," said Washington. "I go to open heart surgeries whenever I can or brain surgeries whenever I can. That just helps me keep my edge."
"The best thing for everybody involved, I feel, is that Derek and Addison really should be together," she said.
"It kind of gets me relaxed and ready to roll," he . Of course it does.
"[They're] from articles that we find in the paper or sometimes we sit in a room and say, 'Is this possible, could this happen', run to the door, ask our medical researcher, 'can this happen,' and she comes back and says, 'yeah you can impale two people on a pole and they can still be talking,' or 'yeah an entire hospital staff can get syphilis,'" said .
Washington used a homophobic slur in regard to co-star T.R. Knight and was subsequently fired. As a result, his return to the show in 2014 sparked a major .
