About 20 years ago, I sent the sales manager at my job a radio commercial script I'd written. I'd cast myself in the role of Drew, figuring it was a natural fit. The sales manager emailed me, joking, "I'd rather have Drew Barrymore in the role of Drew, but I guess if she's unavailable, you could."
So, I was the second choice. That's OK, though, as long as you get the gig.
