In 2005, John appeared in the short film Starcrossed with Marshall Allman from Prison Break. The film won First Prize for Best Drama at the PlanetOut Short Movie Awards in Miami, Florida.
John says his favorite episode of The Flash was "Twin Streaks" because it gave him the chance to "stretch a bit" as an actor. In the episode Shipp not only played "The Flash," but his clone as well.
John: (about being on "Guiding Light") There was a big buzz and a lot of excitement about Daytime in those days. It was amazing in New York City how many fireman and policemen would stop you and recognize you, because in the firehouse during the day they'd have the show on. It was just a lot of fun.
John: In and of itself, my time spent on Guiding Light and As the World Turns stands alone. It wasn't just a stepping stone. I think a lot of actors in any media would love to attempt the kind of stories I was playing.
John: (on starring on "The Flash") My first impression was 'No, I don't want to do a television treatment of a super-hero,' because my experience with that had been the old Spider-Man series when somebody held a rope off-camera, and I knew I didn't want to run around in a pair of red tights. But I read the script and thought that this, even free of it's comic book roots, was a character that I would enjoy playing.
