Slade Wilson will appear in the ninth episode called Patriot  and the eleventh episode called Icarus. We'll only know him by the name Slade when we meet him and he will be played by Michael Hogan, the actor known as Colonel Saul Tigh on Battlestar Galactica.   

I don't know him but visually doesn't remind me of DS.

too old

Burn

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!
WHY TO RUIN HIM ON THIS TV SOAP OPERA, ABOUT LANA LANG!!!!!
I mean, is not about Superman, becuase, if it was, they will decide that she most die, in a horribly way.
I mean Kristin Kreuk, is by far the worst actrees, i ever saw.

i literally watched the entire episode through and didn't realize he was Slade until reading it just now. He was a vast dissapointment. If you want somebody to play deathstroke, you get a young guy with some type of martial art training and acrobatic talent and color his hair white( off the top of my head Ray Park comes to mind), not some old guy with male pattern baldness. 

At this point I think they just used the name because clearly the Smallville character wasn't suppose to be anywhere near the comics version.
