J.R. Bourne has been cast as DC Comics' villain 'Double Down'/'Jeremy Tell' for the fourth season of The CW's Arrow, according to The Wrap.

In the comics, Double Down is a villain that tends to battle The Flash, not Oliver Queen, but for the television universe he'll make his first appearance--3rd episode--in Star City.

For the show, he'll be a metahuman that can "can turn his playing card tattoos into deadly weapons." But in the comics, Double Down was a gambler that gained his powers from a cursed deck of cards that came from a man he murdered after losing to him in a high stakes poker game. Double Down is a sore loser!

The 45-year-old Canadian-born actor is best known for playing 'Martouf' from Stargate SG-1 and 'Chris Argent' from MTV's Teen Wolf.

Arrow’s fourth season premieres October 7th at 8:00PM on The CW.
