Jack Coleman stars as the mysterious H.R.G. – so named after his "Horned Rimmed Glasses." Seemingly an unassuming family man as Claire's (Hayden Panettiere) father, H.R.G. is also a man of mystery who has a special interest in people with special abilities.

Coleman has performed on Broadway, off-Broadway, in film and on television. Series roles include "Dynasty," "Nightmare Café," "Oh Baby," and "Steven King's Kingdom Hospital." Recently, he has been featured on such programs as "Entourage," "Nip/Tuck," "Without a Trace" and "CSI Miami."

On stage, Coleman starred on Broadway in Bill Cain's "Stand-Up Tragedy" in a part he originated at the Mark Taper Forum. He was nominated for a Los Angeles Drama Critics' Circle Award for his performance. He reprised the role in San Francisco at the Marines Memorial Theater and in Connecticut at The Hartford Stage Company before opening in New York. Coleman won a Los Angeles Drama Critics' Circle Award for his performance in John Godber's "Bouncers" at the Tiffany Theater. He also starred off-Broadway in Simon Gray's "The Common Pursuit."

Coleman has also appeared in regional theaters across the country, playing Danny Zuko in "Grease" from Long Island, New York, to Odessa, Texas (where his character in "Heroes" resides), and performing "Othello" and "Loves' Labours Lost" at the Globe of the Great Southwest.

Coleman wrote, produced, and starred in a short film entitled "Studio City," an audience favorite at such film festivals as the Los Angeles International Short Film Festival and the New Orleans Media Experience. He has recently completed a screenplay entitled "Can't Help Falling," a comedic drama about a young man who falls in love with his uncle's fiancée.

Coleman is a graduate of Duke University, the National Theater Institute at the Eugene O'Neill Theater Center in Connecticut, and the Writers' Boot Camp in Santa Monica, California. His grandfather, Herbert Agar, won a Pulitzer Prize in history for "The People's Choice," about how Americans choose their president. Jack's sixth generation grandfather is Benjamin Franklin. His birthday is January 21.
