After months of anticipation, The Flash finally makes its debut tomorrow night on The CW. Over the past week, we’ve been counting down to the premiere by talking to some of the great actors bringing Barry’s adventures to life. While they’re all very unique in their own ways, there does seem to be a clear common thread among the cast—fun. Each and every one of them is a lot of fun and it made us wonder… What’s it like on the set?

The Flash shoots up in Vancouver, and while that’s a bit far for a day trip, we asked our friend Candice Patton (Iris West) to shoot a few set photos for us during some of her downtime. Enjoy this exclusive behind-the-scenes tour of Central City, and be sure to watch The Flash tomorrow on The CW at 8 p.m. (7 p.m. CST)!
