Roy Conli is a producer with a long track record at Disney. His producing work stretches back to The Hunchback Of Notre Dame, and since then, he’s also produced the likes of Treasure Planet and Tangled.

His latest? That’d be the Disney/Marvel crossover Big Hero 6. We sat through a short footage presentation from the film, that we don’t spoil in this article, and then got the chance to chat to the man himself about it. Here’s what he had to say…

Let’s start with some Back To The Future Part III parlance. There’s a bit in that film where Doc Brown gets the train to absolutely the point of no return. At that point, you are absolutely, fundamentally committed to it. Big Hero 6 is an odd project for lots of reasons, and off the Disney track. So where was the point of no return bit, and was a little scarier than some other recent Walt Disney Animation Studios productions? Where was the eureka moment?

It’s interesting. We do a series of screenings every 12 weeks. There was a point, and quite frankly relatively recently. February [this year] I knew we had a film. And then in April, I went ooh, we have a good film. And then in June, I went oh, this is going to be really interesting. And it’s interesting because the way we work, the stories always come late in the game.
