I used to have the most visceral response to having my photo taken. I felt like instantly bursting into tears and running out of the room. I hated all the attention, which is such a stupid thing for an actor to say.
I was mainly influenced by the Carter Family, Jimmie Rodgers, Loretta Lynn, Merle Haggard, and others like Bob Dylan, Johnny Cash.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
