Kate Hudson and Zach Braff star as husband and wife in Wish I Was Here

Kate is brilliantly cast in Wish I Was Here, a bittersweet, offbeat comedy that sees her play a beleaguered mum struggling to keep her unconventional, sometimes dysfunctional family afloat.

The film really gets under the skin of family relationships, a subject close to Hudson's heart.

The star has two sons - Ryder, 10, from her relationship with her ex-husband Chris Robinson, and three-year-old Bing with her fiancé, the Muse frontman Matt Bellamy.

She is famously close to her movie star mum Goldie Hawn and her actor stepfather Kurt Russell and she tributes their parenting as an inspiration for her own.

"I love my mommee!" she exclaimed, when asked about their bond.

"Someone goes, 'What are you first, a parent or a daughter?' and I’m like, 'A daughter!' I’m obviously always a parent but I was a daughter before I became a parent and so that relationship defines how I am as a parent.

"Everyone always talks about my mum forgetting that I had a very present father," she went on. "Kurt and my mum together were an incredible dynamic for parenting. They were very different but their values are so similar. You’ve got two completely different personalities, grounded in the same value systems. And so it was a really interesting upbringing.

"You have the tough dad and the real compassionate mum. Family’s everything to them. For me growing up, the main value growing up was to be honest with each other and truthful even if the truth hurts.

"I definitely bring that to my family and with my children. I liked how honest my parents were, even when they made mistakes. Nothing was hidden, there was no sweeping anything under the rug – everything was really out there and open as a family.

"We were a really close family. We’re still to this day really close. There’s no tricky relationship between siblings or between parents, we’re really super solid. So I hope that I can do that with my kids. I hope I can create that kind of longevity in family relationships."
