I think it was really crucial that the actress was age appropriate. There are films, such as An Education, where that wasn't the case, and I think that really affects how you receive what you're watching.
I had invited 50 or 60 peers and friends, most of whom were parents, to see the film [Trust], and I asked about the last scene. It was interesting because it was split right down the middle, 50/50. About half the audience wanted it to end with the very emotional scene between Clive and Liana, and that feeling of realization and catharsis. And, the other half were adamant about keeping that last scene.
It was really interesting to be editing the film [Trust] in New York and directing the play in Chicago, and one definitely informed the other. The play probably benefitted more because I realized what scenes could be cut, and I cut those scenes from the play.
Directing takes a lot longer than acting. This was about seven years in development, and then two and a half years with pre-production, production, post and now the release. Not that I have people banging on my door to star in movies, but it takes me out of the acting game for a longer chunk of time.
