Valerie Harper said she wouldn’t let terminal brain cancer get in the way of living her life.

The “Rhoda” actress is living up to that promise after Harper, 73, started work on the television movie “The Town That Came A-Courtin’” in Canada.

Filmed for the UP cable network, the film started production Wednesday in Vancouver, according to an exclusive report posted on The Wrap. The movie, named after and adapted from the bestselling novel, also stars Lauren Holly, Cameron Bancroft and Lucie.

"UP is thrilled to have the always inspirational Valerie Harper as part of our talented 'The Town That Came A-Courtin"' cast," UP's senior vice president of original programming, Barbara Fisher, told The Wrap. "Joined by Lauren Holly, Cameron Bancroft and Lucie Guest, this uplifting, sometimes bumpy romance showcases how a community’s spirit and good will can help people connect and find each other."

Harper was cast as Charlotte, a bed-and-breakfast owner in Bliss, the fictional town created by author Ronda Rich.

The “Mary Tyler Moore” actress announced in March that she was diagnosed with terminal brain cancer and had as little as three months to live. But Harper vowed not to let the diagnosis control her life.

The actress was optimistic during an interview on the “Today” show shortly after she announced the diagnosis.

"The thing I have is -- is very rare and it's serious and it's incurable . . . so far," she said. "So I'm holding on to the 'so far.'"

Barbara Fisher, head of programming for the UP network, which specializes in airing uplifting films and television shows, said the network was looking forward to partnering with Harper.

"When I learned that the remarkable Valerie Harper was interested in working, I was so excited, because that meant she was doing well," Fisher told the Associated Press. "We are thrilled to have this iconic talent in our film and awed by her determination to live each day to the fullest. She is truly an inspiration."
