Making a film is hard because you're not dealing with the intangible. When you're writing, it's perfect because it's only in your head and then you have to take it into the physical world and that's where things drop off and things fall apart and you have to fix them.

I often find in the film world, that it's very self-referring. If you talk to someone about films, they talk about them in terms of other films - rather than as something that happened to them in their life. And I'm really keen to get back to film as a reference to real things, not necessarily to other films.

The whole process of filmmaking can be chaotic, but if you can have an enthusiastic cast, you're pretty much there.
