[Any] story [has to be] complete in itself. If there are gaps that you’re hoping will be filled in with visual effects, you’re likely to be disappointed. We can add ideas, we can help in whatever way that we can, but you want to make sure that when you read it, it reads well.

[Our responsibility as VFX artist] I think first and foremost [is] to engage the audience. Everything that we do has to be part of the audience wanting to sit there and watch that movie and see what happens next. And it’s a combination of things. It’s the drama of the characters. It’s maybe what you can do to a scene to make it compelling to look at, the realism that you might need to get people drawn into that moment. It could be any number of things, but it’s really about just making sure that you’re always in mind of how the audience is experiencing what they’re seeing.
