I'm going to be an extra on a film

I'm going to be an extra on a film (that's what you call an accurate post title). I am either a station master or a train conductor. But my colleague Richard gets to be an Gentleman and has huge tophat not a flat small one like mine. I have such hat envy.

I don't know what the films called, who's in it, what it's about and may even be a foreign picture. But I get paid so what else matters.
