Stephen Amell Wears 'Flash' Hat On 'Arrow' Set & It Makes JJJ Insanely Excited

Stephen Amell slips his shades back on his face after arriving at the Marine Building in Vancouver, Canada on Monday morning (July 28).

The 33-year-old Arrow star was still sporting his Flash ball cap as he headed inside to film interior scenes for the show.

“This guy killed it yesterday. Thanks for letting me join you for a sec @amelladventures. Also, for wearing that hat all the time…” channel-mate and Flash star Grant Gustin posted on Instagram over the weekend at the 2014 San Diego Comic-Con.

Caity Lotz, who is back as a baddie this coming season of Arrow, was also spotted around the convention.
