On her own in Indianapolis, Ann Romano was raising two teenage girls — played by Mackenzie Phillips, already famous for the film "American Graffiti," and a previously unknown Valerie Bertinelli. "One Day At a Time" ran on CBS until 1984, by which time both daughters had grown and married, while Romano had remarried and become a grandmother. During the first seven of its nine seasons on the air, the show was a Top 20 hit.
Like other Lear productions such as "All in the Family" and "Good Times," ''One Day at a Time" dealt with contemporary issues once absent from TV comedies such as premarital sex, birth control, suicide and sexual harassment — issues that had previously been overlooked by TV comedies whose households were usually headed by a husband and wife or, rarely, a widowed parent.
Writing in her 2009 memoir "High On Arrival," Phillips remembered Franklin as hardworking and professional, even a perfectionist.
"Bonnie felt a responsibility to the character and always gave a million notes on the scripts," Phillips wrote. "Above all, she didn't want it to be sitcom fluff — she wanted it to deal honestly with the struggles and truths of raising two teenagers as a single mother."
In her 2008 memoir "Losing It," Bertinelli noted that Franklin, just 31 when the show began, wasn't old enough to be her real mother.
Even so, wrote Bertinelli, "within a few days I recognized her immense talent and felt privileged to work with her. ... She was like a hip, younger complement to my real mom."
