Making movies is a very different experience in a lot of ways. It's difficult when you're used to owning the copyright and having a landlord's possessory rights - I rent my plays to the companies that do them and if I'm upset I can pull the play. But the only two directors I've worked with are pretty great.
Moby Dick - that book is so amazing. I just realized that it starts with two characters meeting in bed that's how my book begins too but I hadn't noticed the parallel before two characters forced to share a bed reluctantly.
