Fred R. Conrad/The New York Times Jeremy Jordan as Jack Kelly, his character in “Newsies the Musical.”

Extra, extra! Hey, look at the headline! By night (and on matinee days), Jeremy Jordan is a Broadway star playing the leader of a feisty gang of turn-of-the-20th-century newspaper boys. Now, by day and in whatever free time he has left, he’ll be playing one of the aspiring Broadway stars hoping to hit it big in a developing musical about the life of Marilyn Monroe on “Smash.”

Mr. Jordan, a Tony Award nominee for his lead role in “Newsies the Musical,” will join the ever-evolving roster of performers on that NBC series in its second season, a person with direct knowledge of plans for “Smash” said on Thursday night. (The person spoke on condition of anonymity because the series has not officially announced its casting decisions.) A casting breakdown for Mr. Jordan’s character on “Smash” describes him as: “Straight, working class from Brooklyn. Sexy, charismatic, musically gifted, but also self-destructive and remote.” (The breakdown adds that the performer “Must be able to sing in a rock and/or soul voice” and that “Ability to play an instrument and dance a plus, but not essential,” which we think Mr. Jordan has down.)

Mr. Jordan is expected to remain in the Broadway production of “Newsies” while he works on “Smash,” whose second season will begin early next year.
