In 2013, Dempsey gushed about his Velocity docuseries, Racing Le Mans.
"When you're in a long show, there's less discovery and more of an endurance of having to be present," the former Grey's Anatomy star said at the time. "I'm not necessarily bored with the show, I'm very grateful that I have a show that's on for 10 years, but I'm not the creator, I'm not the writer. We're coming up on 200 episodes, [now] it's about surviving. There's not a lot of homework that goes into it. You try to be present and not get caught acting. I'm grateful I have the gig, but it's not the same thing as being in a racecar."
