Following the first clip released yesterday, The CW has released another look at this week's episode of Arrow entitled "Suicide Squad", airing Wednesday, March 19. We know that criminals Deadshot (guest star Michael Rowe), Bronze Tiger (guest star Michael Jai White) and Shrapnel (guest star Sean Maher) are brought together for a dangerous mission, but we haven't known much about what this mission entails until now, in this scene where Amanda Waller (Cynthia Addai-Robinson) explains the situation to Diggle (David Ramsey). Take a look, then find out more about this highly-anticipated episode from David Ramsey, Cynthia Addai-Robinson and executive producer Marc Guggenheim.

Aside from Arrow (Stephen Amell) himself, the show is chocked full of characters from the DC Comics universe, including these Suicide Squad members. Executive producer Marc Guggenheim revealed that they have the luxury to wait until the perfect time to bring these characters in.

"We have the luxury of waiting til the time is right and we have the right story and the right actor and just the right moment."

This upcoming "Suicide Squad" episode features Diggle being recruited by his ex-wife Lyla (Audrey Marie Anderson) to take part in a special mission for A.R.G.U.S., which is connected to a man he saved several years earlier in Afghanistan. Joining Diggle will be Deadshot, Shrapnel and Bronze Tiger, characters who had previously been introduced in the series. David Ramsey revealed that the Suicide Squad's formation came about organically.

"Obviously all these characters facilitate the creation and the exploration of the hero. All of the stories lead back to Oliver. What's been most impressive is making these other characters interesting but also still connecting them to Oliver without being heavy-handed."

Cynthia Addai-Robinson also spoke about how she wanted to portray Amanda Waller as an efficient woman, leaving viewers guessing whether or not she's a hero or villain.

"She's pretty no-nonsense and straight to business. There's a stillness in that - she's just one of those characters where she looks at you and you basically know what she's thinking. It's been fun to practice my looks to characters I'm interacting with."

While Diggle didn't originate in the comic books, he has become so popular that his character has been implemented in DC's tie-in comic book series. Here's what David Ramsey had to say about Diggle.

"He's just the regular dude who has this extraordinary responsibility thrust upon him, and really that he's taken upon himself."

Marc Guggenheim also teased that there will be an easter egg related to 1980s Suicide Squad writer John Ostrander, plus a mysterious cameo.

"The comic book fans (in) the audience will lose their mind. We get a chance to bring these characters to life out of the pages of the comic and onto the screen, but the nature of the show requires us to do it in a way that's unique and original and hopefully unexpected."
