1. "It was terrifying. I accepted the job on Monday and started working on Wednesday. I didn’t really have enough time to be scared about it. But, you know, you hit the ground running, and if you can’t keep running—you’re out. So you have no choice but to run with it. It’s pretty amazing. You know, I knew about the dialogue being scary. But I had no idea how technical the actual job is. Physically you have to learn to do things and look like you’re doing procedures and look like you know what you’re doing at all times in a trauma room—where it is life and death. That takes a lot of learning." — Linda Cardellini on her role on ER
2. "The one thing that being on ER has changed is that I’m more recognizable because it’s the first time where I played someone where I look like her on the street. I could stand next to the poster for Scooby-Doo and nobody would know that it’s me." — Linda Cardellini on how ER has changed her
3. "Yeah, if it’s a great story definitely. Kids love it. I hear some 3 or 4 year old kids who can’t speak in complete sentences and they love to talk about Scooby-Doo. It’s fun. It’s really a great character. There’s not a lot of broad, young and smart, crazy, zany characters that you get to play like this." — Linda Cardellini on whether she would do a third Scooby Doo film
