I can't comment on any outside perception. I'm happy to come out and talk about movies that I've worked on in a setting like this. Otherwise, I have my own life that I live which is very different and private. ↗
I think the only boundaries are individual and personal. A writer should be free to write about anything he or she wants to, including the twin towers. I have made small references to 9/11 in my past two books. ↗
