In a recent interview with Vulture Michael C. Hall fesses up:
When you landed the role of Dexter, didn't you actually practice stalking people in the city?Italics mine. As a single woman that was by far the most comforting tidbit I've read all day. Can I get an "Amen!" from the other
[Laughs.] I pretended to stalk people. I wasn't actively stalking people, but I did follow them. If there was somebody alone, I'd follow them around, just to see what it felt like — no syringe, though. Maybe go down on the subway and stay a car away. Try not to get noticed, just to see what it felt like.
Did you ever get caught?
No. I never got caught. I know! [Laughs.] The key was distance: Don't get too close, and if you feel like you might be spotted, relocate, cross the street. It was pretty easy, especially if it's the busy part of the day. I learned if you're out and about, you're probably being followed by someone — so don't go down those deserted alleyways! It was kind of creepy. I creeped myself out.
