Fans were hoping so hard for Michael Rosenbaum to return to the CW’s Smallville before the series’ ten season-long run came to an end and boy are they getting their wish! As SciFi Mafia reported to you in February, after much urging by Tom Welling, Smallville fans, (and no doubt his agent,) Michael Rosenbaum is indeed returning to Smallville as Lex Luthor in the two-hour season finale on May 13, 2011 and now, we have our first look at the finale and the long-awaited return of Lex Luthor. Check out the preview below:

When asked how was his experience with his return to Smallville, Rosenbaum told TVLine that it was like a family reunion:

“I have to say, that was the most amazing time, going back. There were people who worked on that crew that aren’t even working on the show anymore that came to see me. It was like a family I hadn’t seen in a while. People don’t know this, but I got nervous. I was really nervous. To jump back into that role and start quoting Sun Tzu, and I’m looking at Tom…? It felt so surreal. I was going, “Can I do this?” And finally you just do it! And believe it or not I’m actually glad I shaved my head all those years, because the bald cap [used in the series finale] is a bitch! It took like 2-1/2 hours to get on, and it is not the most comfortable thing.

I really didn’t want the day to end. Once you’re there, you always want more. Like, ‘Oh c’mon, this is fun. Write something else!’ ”

As for Rosenbaum’s Saved By Zeroes project with Jonathan Silverman about two former sci-fi stars, Rosenbaum gave a quick status update:

“That was a disconcerting experience. We sold it to Syfy, Happy Madison was producing it, and the president of Syfy was all in. But then it wasn’t his choice; it came to [someone else], and then it kind of fell through. We couldn’t believe it. But we’re getting it back and we’re going to try to go elsewhere. If I have to spend my own money, I’ll make it myself.”

You can currently see Rosenbaum on Fox’s Breaking In as Dutch, a character most unlike Lex Luthor. His Breaking In character plays on Rosenbaum’s comedic talent and ability to create a character that you can’t help but like. Seriously, who else can carry off an opening line of “Hey, you look smart. Can I have some urine?”
