One look at Tamara Tunie’s resume and you wonder when she sleeps.

The TV veteran isn’t a household name, but she’s quietly become one of the most prolific actresses in Hollywood — appearing, in the past year alone, in “Blue Bloods” (CBS), “Dietland” and “Better Call Saul” (both on AMC) and the BBC’s “Black Earth Rising.”

“I feel like I’ve always been working under the motto that ‘work breeds work,’” says Tunie, 59, who’s also been a staple of mainstays such as “Law and Order: Special Victims Unit” and “As the World Turns.”

“For me it’s not always about what’s going to pay the most money,” she says. “It’s also about what I find the most compelling. I’m willing to participate in a variety of different [projects], and not just based on a pay grade.”

Up next for Tunie is BET Her’s first original movie “Her Only Choice,” (Saturday at 9 p.m.), which follows a young woman (Denise Boutte) whose life is upended when she discovers that she’s pregnant —and gets a breast cancer diagnosis at the same time. Tunie’s character, Brenda, is her mother figure.

“Her Only Choice” is part of BET Goes Pink, a month-long campaign to educate and empower African-American women about breast cancer. (October is Breast Cancer Awareness Month.)

“I haven’t personally [experienced breast cancer], nor has anyone in my family, thank God,” says Tunie. “But certainly I have friends who have had to deal with this issue. A dear friend is a breast cancer survivor of some 15 years or so.

“Most recently, I have a very close friend who’s like a mentor, who’s in her 80s who actually was diagnosed with breast cancer and had a double mastectomy in her early 80s, which is very traumatic.

“I just fortunately have been able to be as helpful and supportive to both of them as I possibly can.”

Although she grew up in Pittsburgh, Harlem has been Tunie’s home for the past few decades.

“I’ve been a Harlemite, a Harlem girl, pretty much the entire time I’ve been in New York city. I’m really proud of that,” she says. “I feel like the city has been really good to me, over the past 30 years. Also I feel like I’ve brought and given a lot to the city. I was honored with a ‘Made in New York’ award from Mayor Bloomberg’s administration from my support of and participation in the film, television and theater industry —and that was very important to me.”

In her downtime from acting, Tunie still doesn’t slow down. Later in the year (at an unspecified date) she’s releasing a CD with “a variety of different kinds of tunes,” she says. “Some jazz standards [and] some R&B tunes I’ve reworked in a jazzier kind of way,” she says. “I sing live pretty regularly — club dates and that kind of thing. But this is the first time I’m going into the studio to record.”
