'Arrow' Season 3 Spoilers, Latest News: New Villains Threaten Starling City, Filming Wrapped

The CW's hit superhero TV series "Arrow" leaves its fans wanting for more action following its explosive Season 2 finale. Now that Season 3 is already around the corner, viewers are now yearning for spoilers and revelations on what will happen to the billionaire playboy and vigilante Oliver Queen, who is played by Stephen Amell. Here's what we know so far.

Numerous reports indicated that the forthcoming season will see other superhero names like The Atom (Brandon Routh) and Wildcat (JR Ramirez). There are is also Peter Stomare as Werner Zytle/Count Vertigo and David Cubitt as the Manhunter.

The most notable character introduced is Batman's former mentor-turned-enemy Ra's al Ghul. As reported, he will be instated to be the main antagonist throughout the coming season.

The villain, as often portrayed bearing a rather radical idea of a perfect world, will carve a much darker path which the hero will tread on.

David Ramsey, who plays John Diggle, explained the direction of the new season.

"The big heavy is someone who will bring a lot of darkness -- even more so than Barrowman's Merlyn or Manu's Slade," he said in reference to the antagonists in the previous seasons.

Other scoops from the people in the know indicated the participation of Glee alumnus Nolan Funk, who has made cameos on other superhero flicks like X-men and Riddick, as Cooper Seldon. He will be Felicity Smoak's (Emily Bett Rickards) ex-boyfriend in fifth episode of Season 3 entitled "The Secret Origin of Felicity Smoak."

Meanwhile, further news indicated that filming for "Arrow" season 3 is already complete.

"Wrapped Episode 50 of #Arrow last night with a scene two years in the making," Stephen Amell tweeted.

Season 3 of "Arrow" will premiere on October 8 on The CW with the episode entitled "The Calm."
