This ought to make you feel old: Greg Grunberg has been a television staple for more than a decade now. He’s been acting for even longer than that, of course, but with no small amount of help from his good buddy J.J. Abrams, Grunberg has managed to maintain a steady presence since 1998, when we were introduced to him as Sean Blumberg on “Felicity,” and from there, we came to know him as Eric Weiss on “Alias.” For the past three seasons, however, he’s been Matt Parkman, the man who messes with your mind every week on NBC’s “Heroes.”

“You will not ask me about my role as Brett in ‘Malibu’s Most Wanted.'”

Bullz-Eye will be talking to Mr. Grunberg in connection with the appearance of “Heroes” on our upcoming TV Power Rankings, and we’d like to give the dedicated readers of the show’s blog the chance to ask him some questions. Whether it’s about his character’s relationship with the late, great, and supercute Daphne, the recent revelation that Matt Parkman has a son, or if you just want to know if he spent hours in front of the mirror to perfect the look he gives when he’s using his powers, just leave your questions in the comments section and we’ll add ‘em to our list. Then check back here and on Bullz-Eye.com on April 15th to read their responses…and, of course, to find out where “Heroes” turns up in the TV Power Rankings!
