Via THR: Michael Ironside will appear as Lewis Snart, the “estranged, abusive father” of Leonard and Lisa Snart, a.k.a. Captain Cold and Golden Glider.
The apple doesn’t fall far from the tree, as Lewis is described as cold-blooded, ruthless career criminal. Recently released from prison, he returns to Central City with a plan that will endanger both of his children.
Ironside will appear in the third episode of The Flash season two, “Family of Rogues,” along with Cold (Wentworth Miller) and Glider (Peyton List).
Now I’m trying to remember if the Snarts’ father had a canonical first name in the comics. All I remember is a few Flashbacks and the horribly miscalculated hostage-taking attempt in Final Crisis: Rogues Revenge.
