I don't know what any of my songs are about. I don't sit down to write about anything. They're about whatever you want. I don't pick subjects. I just start.
You're not there to spread any particular- if you're Bob Marley you're there to spread a message, but very few people can do that effectively without shoving opinions down someone's throat.
I like to rehearse with the actors scenes that are not in the script and will not be in the film because what we're really doing is trying to establish their character, and good acting to me is about reacting.
