Just a few weeks ago, Dan Rider was simply another "Whovian," a "Doctor Who" fan who was particularly psyched to see the much-anticipated "Let's Kill Hitler" episode.
He was so excited that he was inspired to do an a capella version of the show's iconic theme song, backed up by, well, himself. Check it out:
His clever editing job, and unabashed love for the series caught the attention of executive producer Steven Moffat, who tweeted it with the words, "Made my day!"
CNN spoke to Rider to ask him about his moment of viral video glory.
CNN: What inspired you to do this video?
Rider: I'd been wanting to put lyrics to the "Doctor Who" theme ever since I realized that "Alons-y, Alonso" fit perfectly with the tune. I mulled for a few months before being able to finish the rest. And one night, at about 1:00 in the morning, I decided that it would be a great idea to do the whole thing a capella and with a construction paper fez (had I been more awake, I probably would have thought it was a terrible idea, but there you go).
CNN: How long have you been a Whovian?
Rider: I've been a fan for the past 2 or 3 years, ever since my girlfriend got me hooked on the new series. At first, I didn't think anything could pry me away from "Firefly," but I very quickly found myself staying up all night to watch the episodes endlessly on Netflix Instant Play. I don't think I slept a full night until I caught up.
CNN: What makes you so passionate about the show? The theme song?
Rider: It's a show of such complexity, humanity and heart, I can't imagine anyone not being passionate about it. Aside from that, the show personally inspires me with it's incredible acting, directing and writing, three things that I'm currently going to college to study. It's personally inspired me to be better at what I do. As for the theme song, my friends and I have a semi-choreographed dance to go along with it. 'Nuff said.
CNN: Have you done much a capella before this?
Rider: I've sung tight harmonies in a lot of musicals, and my high school had an a capella group (we specialized in Life Is A Highway).
CNN: What was it like hearing back from Moffat?
Rider: It was like getting a high-five from Jesus. It was unreal. Being on the radar of one of my idols, even in Twitter world, put me on cloud nine for days.
CNN: How have other fans reacted to your video?
Rider: I'm getting amazing feedback! The "Doctor Who" fanbase is so tight-knit, so nice, and so damn cool, and I'm loving being a part of it. They rock.
