How was this Flash different from your past performances?

Michael Rosenbaum: This Flash is more mature, so he's taking things a little more seriously. But we still had some fun with the character. He's still fun loving, but he's taking business seriously.

What does it mean to you to be back with this group of actors again?

Michael Rosenbaum: It's amazing being back with the old team, to come back here and all be a part of something special. It's exciting. And everybody's really great. We always had a blast. We always were joking. Lots of great guest stars and always a lot of laughs.

What is it about Flash that so appeals to you?

Michael Rosenbaum: I think it's his sense of humor. In most superhero films and shows, everybody takes themselves so seriously - and you need that guy that's going to take the edge off, provide a little levity, give us a laugh to break the tension. He's no less of a super hero just because he's got a comedy schtick. He just knows how to have fun with danger.

Did you ever learn anything about yourself voicing Flash?

Michael Rosenbaum: I guess you learn a little from every character you play, This character is always a kid at heart. I really think deep down with The Flash that it's like this inner child that's just trying get out, and I think that everybody has got to keep that. So it reminds me that you've got to always have fun with things. Don't take work too seriously. Don't wait for the big part, and if you didn't get it, it's not the end of the world. It puts things in perspective. Be like Flash, he kind of goes with the flow.

Do you collect any kind of Flash memorabilia?

Michael Rosenbaum: I have toys at my house. I have Flash toys. I have Superman toys. I have lunchboxes. I have the original lunchbox of "Superman The Movie." It cost me a hundy. It's probably worth $105 now. Mm hmm. I even have The Warriors dolls. Remember The Warriors? One of my favorite things is an original Justice League painting by Alex Ross that hangs in my guest room. Alex is a genius. I was at this convention signing autographs. And I'm a nerd. Whenever I'm done signing, I want to go walk around like the fans because that's who I am. So I was walking around and I saw this amazing painting that was going for $2,000 and this guy says, 'Don't buy it, I know Alex.' So sure enough, Alex sent me one about a week later to my house. And then I met him later on. He's a great guy. He did my Lex Luthor portrait for TV Guide way back when.

What were you thinking coming back to the studio to record for the first time as Flash after all these years?

Michael Rosenbaum: I made sure that I got some sleep last night before I came to the studio because I knew that I had to really bring my A-game to Bruce (W. Timm) and Andrea (Romano) and the crew. The great thing about voice work is that you don't have to worry about too much because you work with a great team. You just kind of sit down and relax and have water and a bag of chips and you just say the lines until you get them right. The funny part is that, when you're alone in the booth, sometimes you don't have anybody else to talk to. You're just looking out through the glass partition, and if they don't want to hear you, they just let go of the button and you sit there talking to yourself. So I sit alone in this big room and I just kind of read copy. As long as you can read, you're okay.

You've worked with Andrea Romano for a long time. What makes her so special at what she does?

Michael Rosenbaum: She is the best in the business. She knows the material. She knows exactly what's happening at every moment. And she doesn't make you feel stupid. She's become a dear friend, sometimes she comes to my Thanksgiving dinners. Bruce doesn't. Okay, maybe I don't invite him. But with Andrea, she takes her job seriously but in a fun way, kind of like Flash. What's really funny about Andrea is that she'll sugarcoat things. You'll know you sucked on a read, but she'll make it sound like you didn't suck - but still get you to do it better. For instance, she'll say, 'That was really great, except this time you're a little more serious,' or 'Maybe with a darker tone,' or something that directs the actor without deflating him. She makes it playful and fun.

What was your reading of choice when you were a kid?

Michael Rosenbaum: I didn't really have a strong comic book relationship. I had more Fangoria magazines than I had comic books. I'm a big horror movie nut. Most kids would come home and do milk and cookies. My mother had milk, cookies and "Motel Hell." This is the crap I watched and this is why I can't sleep. I have an alarm system and a dog and a baseball bat next to my bed. But for some reason, I still watch horror movies. I actually directed a horror short called "Fade Into You." Check it out sometime. I got these great horror actors - AJ Bowen and Danielle Harris -- and we shot it at my house for two and a half days and nights. It was a blast.

You've played Lex Luthor and you've voiced Flash. Is there a character that your inner geek is craving to play?

Michael Rosenbaum: I think I'd be a fantastic Han Solo. Unfortunately, Harrison Ford played Han Solo. But I think that's my personality. Maybe someday they'll do a series where I could play Han Solo. Who knows? A guy can hope.
