after Wilson's arrival, the character of Ginny Wroblicki proved to be unpopular with viewers, and Wilson herself did not like the role or get along with Franklin. Wilson wrote that "aside from Lear, nobody thought I was funny...To make matters worse, each character, according to the show's formula, had to have a 'serious' moral dilemma at some point, and I was given some problem about an illegitimate child to work out in these increasingly sentimental scenes that made my bowels shrink." At the end of the second season of One Day at a Time, Wilson was released from the show at her own request after appearing in 14 episodes. The character of Ginny Wroblicki was never seen, referred to, or heard from again except in a fifth-season retrospective clip episode. For the next two seasons, the central cast of Ann, Julie, Barbara and Schneider was supplemented by recurring characters, including William Kirby Cullen as Julie's boyfriend Chuck Butterfield, Howard Morton and K Callan as Chuck's parents, John Putch as Barbara's awkward friend Bob Morton, Scott Colomby as Barbara's boyfriend Cliff Randall, and John Hillerman and Charles Siebert as Ann's bosses, Mr. Connors and Mr. Davenport, respectively. Dick O'Neill and Nedra Volz made three appearances together as Orville and Emily, residents of the retirement home where the main characters put on a semiregular variety show. Joseph Campanella also made several appearances as Ann's ex-husband and the girls' father, Ed Cooper. Michael Lembeck joined the series as Julie's husband, Max, in the fifth season, but he was written out as a consequence of Phillips' firing (but later returned in season seven along with Philips). A steady stream of regulars was added in the ensuing seasons, including Ron Rifkin as Ann's boyfriend, Nick; Glenn Scarpelli as Nick's son, Alex; and Boyd Gaines as Barbara's boyfriend, later husband, Mark. Shelley Fabares, who had previously guest-starred as Ann's rival co-worker Francine Webster, appeared more frequently, eventually becoming a regular. Nanette Fabray, who played Ann's mother, also made more frequent appearances before becoming a regular cast member in the final season. Howard Hesseman joined the series for a short time as Mark's father, Sam, who would become Ann's second husband. Notable guest stars throughout the series run include Norman Alden, Robby Benson, Carla Borelli, Charlie Brill, Dennis Burkley, Jack Dodson, Elinor Donahue, David Dukes, Greg Evigan, Conchata Ferrell, Corey Feldman, Alice Ghostley, Lee Grant, Mark Hamill,
