Exclusive: Big Miracles narrator Lisa McCune opens up about working on the groundbreaking new series

The thought of starting a family once you meet The One seems like a pretty simple next step, but it's not always easy. 

Channel 9's groundbreaking new series Big Miracles explores what happens when couples have to go down the path of IVF. Australian actor Lisa McCune joined Big Miracles as its narrator and spoke to 9Entertainment about being a part of the project.

"There seems to be a lot of really great documentaries on so many different things and I particularly love the subject matter in this because it's about families," McCune said. 

"It's about how, I guess, you start a relationship and then the next step is having a family, and then if you hit a roadblock it can be really trying and really traumatic, it all seems so easy up until that point and then you've got to really tackle it."

The series focuses on 10 couples who are hopefully on their way to becoming parents. McCune has loved following their journeys.

"It's almost like you manifest this person that's not there yet," she explained.

"You kind of have such a strong attachment to that baby that you haven't met yet and you really feel a very strong connection and it's a wonderful, wonderful piece of television."

As you can expect, it's an emotional rollercoaster for the couples and one McCune admits she got very sucked into as well. 

"The night before [I record the narration] I watch the episode through before I go into the studio to voice it, and I don't think that there's been an episode where I haven't cried," she said. 

"I don't know if that's because I'm a mum and I'm emotional, I know people who have had struggles with getting pregnant and the difficulties and people who have lost children. It's really emotional.

"It feels like it should be the most natural thing in the world and it really somehow gets to the core of humanity, I've loved it."

The series explores all of those things, but it also goes into the emotional issues and of course the financial side of IVF and fertility treatments too.

"We expect so much these days, we feel like we can have anything, but then maybe sometimes we just can't," she said.

McCune, who is mum to three kids, was fortunate enough not to go down the road of IVF when it came to falling pregnant, but she's found the science behind it all so interesting.

"What really fascinates me is the science behind it because the documentary every week talks about the science of getting pregnant and it really does explain it," she said. 

"You start to go wow, getting pregnant in the first place is difficult, but then when you have problems – and science can identify now and work out exactly why it's not happening.

"They're really able to pinpoint it and get quite specific about how they treat and that to me is really wonderful."

While the series will show the success stories and joy of falling pregnant for some couples, viewers will also see the emotional reality of failures.

"But although science can do a lot, sometimes it just doesn't work," she added.

The filming for the show took place over at least 12 months and it's one part of the process that McCune found "fascinating". 

"I think that to me is what is truly fascinating, the fact that this has been going on, involving families and babies and of course trying to get pregnant, there's been a lot of time leading up to the actual filming and then the filming itself and then the post-production," she explained.

One big thing she has taken away from being a part of the project is how many women are now turning to egg freezing, something she doesn't recall really being an option when she was considering starting a family. 

"The fact that there's these really clever, smart young women who are thinking, 'I haven't found the right person, but I want to have children one day'," she said.

"IVF gives them the opportunity to freeze some eggs, that is obviously the key to some of the stories.

"And I really celebrate the fact that some of these young women are so savvy to own what they want enough to freeze their eggs, it's great."

Big Miracles premieres on Monday February 6 at 9.00pm on Channel 9 and 9Now.
