"Superman Returns" star Brandon Routh is about to return to the DC Universe -- but not as the Man of Steel. TV Line reports that Routh has been cast as Ray Palmer/The Atom in the CW's "Arrow" season three.

Described as "an unparalleled scientist and inventor," the "Arrow"-verse version of Ray Palmer will come into Oliver Queen's world as the new owner of Queen Consolidated and a possible new love interest for fan-favorite character Felicity Smoak. "Arrow" is The Atom's live-action debut -- though the character has featured in many different animated iterations of the DC Universe.

Although Routh is best known for playing Superman in 2006's "Superman Returns," his other notable roles include evil-ex Todd Ingram in "Scott Pilgrim Vs. The World"; a recurring role as Agent Daniel Shaw in the fan-favorite television series "Chuck"; and a minor role in "Zack and Miri Make a Porno."

"Arrow" season three is set to debut Wednesday, October 8.
