Inside Out: Producer Jonas Rivera states that the Disney film is a 'love letter' to his children

With a film like Inside Out, it's far too easy to find yourself in mushy territory when considering its emotion-filled subject matter, and it seems as if the film-makers behind the movie aren't exempt from talking about their feelings either.

Talking at the London press conference in the run-up to the Disney Pixar film's UK release, producer Jonas Rivera, joined by director Pete Docter and star of the film, Amy Poehler, was asked by Cover Media what his personal definition of joy was.

A question to which he effusively answered: "I feel like we have the greatest jobs in the world – I never dreamed I'd be here in front of you in this great city with a film that we spent five years of our life on that we're so proud of, it's a love letter to our kids.

"It's obviously our families, to me, that bring our greatest joy. But, I also happen to have this job that I could not feel luckier to have.

"To work with people like Amy and my best friends on making things – we get to make things and put them out to the world. With enough time and care from the studio we hopefully can craft them into being meaningful."

The upcoming movie has earned overwhelmingly positive critiques since it opened in the US a couple of weeks ago, but it originally became 2015's movie to beat at Cannes Film Festival where it received a 10-minute standing ovation from its audience – a reception that Rivera didn't necessarily expect.

"We were so blown away to be there, it was such an honour to be asked to go there. Honestly, it was probably the most nervous I've ever been in my life.

"Cannes as you know is a very discerning audience and they spent a lot of time warning us," he explained. "'They'll boo if they don't like you, and they don't necessarily like big American movies, and at first, we were like: 'Well, why are we here?!'"

Docter was also surprised by the reaction, claiming that they "walked out of there in a daze", while Poehler joked: "I mean Cannes is ruined for me [now]; there's nowhere to go but down from there."

Inside Out will be released in UK cinemas this Friday (22 July).
