IGN are reporting that Michael Hogan will appear in two episodes of SMALLVILLE. Copy and paste of the article under the LJ cut incase anyone is worried about spoilers.
Smallville: Battlestar Alum Set to Play DC's Deathstroke
Exclusive: Deadly comic book character to debut on the Clark Kent series.
By: Eric Goldman
Date: October 1st, 2010
Exclusive: One of the coolest characters from the DC Comics Universe is coming to Smallville - and the actor they've cast in the role is a very fun and inspired choice.
Slade Wilson will be introduced in the ninth episode of Smallville this season, called "Patriot." We'll only know him by the name Slade when we meet him, but DC fans of course are aware that this is the man destined to become Deathstroke, an incredibly skilled and dangerous mercenary - and IGN's pick as the #32 on our Top 100 Comic Book Villains of All Time list!
Playing Slade will be Michael Hogan, the veteran actor best known for his work as Colonel Saul Tigh on Battlestar Galactica. While his role on BSG called for Hogan to often play a drunken mess, we also got to see plenty of his tough side too, which I'm guessing will be called upon big time when Slade shows up in Clark Kent's life. And while I can't tell you whether Slade will be missing an eye yet when he comes to Smallville, it's hard not to be amused about Hogan already having experience playing an eye-patch wearing character.
Hogan is currently slated to appear in two episodes, including the eleventh episode of Season 10, which is called "Icarus." After that, we'll see if he'll show up again before the show comes to a close at the end of the season. But I know I can't be alone in hoping to see Slade take on the Deathstroke guise!
Slade is the latest addition to a season that will also see the Smallville debuts of Deadshot, Blue Beetle and Booster Gold, on top of the growing threat of Darkseid.
