Grant Gustin Films 'The Flash' With Jesse L. Martin in Vancouver

Grant Gustin carries his forensics case while shooting a crime scene for The Flash on Wednesday (July 20) in Vancouver, Canada.

The 26-year-old actor was joined on set by his co-star Jesse L. Martin.

That same day, Grant posted a cute Instagram photo with his dog hanging outside his trailer.

“Jett’s looking good with his summer cut and I’m easily distracted while taking us-ies of me and the dogs. Gotta use that first take though,” he captioned the pic, which you can see below.
