Video via willowmansdaughter's post on tumblr: 'The Young & Prodigious Spivet: Incarner la famille Spivet'
Behind the scenes with Jean-Pierre Jeunet and the Spivet family, Jakob Davies, who plays Layton in the film, shared a link to this on Twitter, and there are three more behind-the-scenes videos at the source. This one features Jakob, Callum Keith Rennie, Helena Bonham Carter and Niamh Wilson. Short, but very sweet.

Movie trailer excerpt, with TS. Spivet's voice-over:
Our ranch was located seven miles north of Divide. My father, Tecumseh Elijah Spivet, was born 100 years too late. He had the soul, stature and the mindset of a cowboy.
Jean-Pierre Jeunet, director:
Callum Keith Rennie who plays the role of TS's father, is an actor who specializes more in TV series, in Canada, mostly cult scifi series. It was a very very beautiful discovery because he's got that real amazing cow-boy face.
Callum Keith Rennie, TS's father:
Well I grew up in Alberta, so there's a sense of that world that was always there. Big sky, country, and all that. So. It wasn't hard. I'm really happy that I had the opportunity to play it.
