Josie Bissett is so in love with being part of the “Wedding March” movies for the Hallmark Channel, she’s starring in the fourth film in the series. “Wedding March 4: Something Old, Something New” debuts 9 p.m. Saturday.

There are three big reasons why the Seattle native and “Melrose Place” star loves the franchise. And, there’s one thing she would change about the tales of romance and marriage.

Her first love with the series is her co-star, Jack Wagner (“When Calls the Heart”). They are back playing Mick and Olivia, the pair who operate the most beautiful place to hold a wedding this side of Cupid’s backyard. Merritt Patterson (“The Royals”) and Andrew W. Walker (“My Secret Valentine”) portray a couple about to be married at the Vermont Inn if the bride can stop trying to please everyone else with her ever-changing plans.

At the same time, Mick and Olivia continue to find it difficult to find a few moments for their own romance.

Wagner, who is also the executive producer of the films, had not found his lead actress when the first movie got the go-ahead from Hallmark. As soon as he thought of Bissett, he knew she would be the perfect person to handle both the comedy and drama of the role. Instead of taking the customary route of contacting Bissett’s agent and setting up an audition, Wagner reached out to her through the internet.

“He contacted me through Twitter direct message,” Bissett says. “I never look at that, so I think it was months before I saw it. It didn’t surprise me that he contacted me that way. That’s just him.”

The pair had only shared a few lines on “Melrose Place,” but Bissett finds the working relationship with Wagner to be incredibly comfortable. Bissett says work is much easier when she’s sharing a scene with someone she likes working with like Wagner. That comfort comes from knowing Wagner for so many years, and how perfectly matched Olivia and Mick are in the movies.

Working with Wagner would be enough to make “Wedding March” movies a joy for her, but the second reason Bissett loves the job is each episode is full of the love and romance that goes with wedding days.

Whether she’s consciously thinking about the wedding aspect of the films, the movies have left a mark. It was less than a year ago that Bissett and Thomas Doig were married at a chateau in the Pacific Northwest that looks a lot like the setting for “Wedding March.”

Bissett was a calm bride for two reasons.

“One, I have done it before. I was not in the moment in my first wedding because I was so worried about everything,” Bissett says. “I vowed I would not do that again. I worried about nothing and just enjoyed everything.

“And, the ‘Wedding March’ movies helped because I got engaged while I was doing them. In the script, a bride would be obsessing about her invitations and I would think, ‘That’s right. I have to get invitations.’”

When not making TV or movie appearances, Bissett, a mother of two, has hosted TV series dealing with parenting, such as the PBS special “Teach More, Love More,” which follows families with a child in a stage of early childhood development. She also hosted “Parenting & Beyond,” a show that offered parents creative solutions to everyday problems. Bissett also found time to co-edit the two parenting advice books “Little Bits of Wisdom” and “Making Memories.”

That leads to the third reason Bissett loves the series. Along with handling wedding issues, Olivia must deal with the news her daughter, Grace (Emily Tennant), and Grace’s boyfriend, Eric (Blair Penner), have decided to get married. But, Eric is going on tour with his band and Grace’s decision makes Olivia recall her own choice when Mick left to go on tour at the beginning of their relationship.

“I have loved being a mom so much. I have loved playing a mom,” Bissett says. “Olivia is full of emotions that she went through but doesn’t want to control her daughter. Everybody evolves in the script the way real humans do.

“My interest in parenting just grew out of my own passion. When my son was born, I still wanted to do something creative. So writing books was a way to do that and control my own time.”

Bissett has continued to work over the years in films such as “The Fire Above,” “Dare to Love,” “Deadly Vows” and “I Do, They Don’t.” She also made numerous guest-starring TV appearances, including “Law & Order: Special Victims Unit” and “The Secret Life of the American Teenager.”

When it comes to “Wedding March,” Bissett loves working with Wagner, the fact the series of films are entrenched in love and marriage and that she gets to play a mom. There’s only one flaw in this paradise. Bissett is convinced the franchise is strong enough to be a weekly series rather than a series of movies.

“I am getting to that point in my life where I would like to settle into another series. My son is going off to college and my daughter is 16,” Bissett says. “The only thing is the series would have to shoot in Canada (where all “The Wedding March” movies have filmed) because it is a two-hour drive for me.”
