Mark chats to the co-directors of Disney’s Frozen, Chris Buck and Jennifer Lee… Jennifer, as a screenwriter, how do you map out the songs that are included in the film?

Jennifer:Its very tricky.

And if it didnt work, Id rewrite everything leading up to it.

The best example of that is Let It Go.

There was a lot of back and forth.

Chris:There was no overlap.

It was a whole new crew, too.

Did everything fall into place quite quickly after that?

Jennifer:Not quickly!

[laughs]

Chris:Yeah, nothing ever goes quickly in animation.

[both laugh]

Chris:But youre right, it really was a key moment.

Emotionally tying these two characters together was something that we were really struggling with.

We had these two women, but having that emotional bond helped us throughout the movie.

It was how we could play with the story and make it as strong as it is.

It allows us to go really deep into what their relationship is.

In every single way, we just kept finding more and more great stuff.

I think thats where we get that very timely, but timeless feeling, with that theme.

How did you go about toning them and getting them right?

So we came from there with each character even Sven, the reindeer.

That was our goal.

How did you marry those darker aspects with the visuals?

Chris:We did a lot of research with our art director and his team.

The way the light refracts, the colours- just so many things were inspired by all of this research.

Jennifer, you were promoted to the co-directors chair relatively late in the production.

Jennifer:[laughs] It was more the second!

Chris and I were relieved though, it just seemed like the right fit.

Jennifer:And we havent fought yet.

Hes a very patient man.

How do you feel about Tarzan now, in retrospect?

Chris:I still love that film.

You have a soft spot in your heart for each movie, and youre doing certain things.

Youre learning as youre going, as a director, and each movie is its own entity.

It had such great music by Phil Collins, and that became the voice ofTarzan.

But each movie is really its own thing.

I loveFrozen, too I love what weve done with it, and I love CG.

I loveTarzanfor that time in my life, and I think its still a great film.

One last question: this is a very snowy movie.

Chris Buck and Jennifer Lee, thank you very much.

Hence, were waiting until more of you have seen the film first!
