Never work with children and animals... at least not this one

I am currently in pre-production for a commercial for a popular cereal product due to shoot at the end of April. The ad will feature a young child. I've worked with children (and indeed animals) a few times over the last couple of years and *touch wood* there have been no huge problems yet. As long as no-one breaks the rules on shooting hours and all the licenses are in place then problems can be avoided.
Never before sitting in on the first casting session for this job have I understood the importance of getting exactly the right child for the job though. A kid's a kid right? Wrong.
We asked one delightful 7 year old if he liked super-heroes.
His response: "No."
Casting director: "Why's that then?"
7 year old: "Cos they're gay."
The room: *Stunned silence.* *Awkward glances.* *Nervous smiles.*
Call me old-fashioned but I'm pretty sure super-heroes were cool when I was 7. I wanted to correct the child that in fact not all men who wear tights are homosexual. And that if a super-hero did happen to enjoy other men sexually then that doesn't make him less awesome. I thought better of it upon considering I might be delving into some trauma he's experienced with his father. Never bring up the daddy issues - it never ends well. Also he's 7, and probably doesn't really understand what 'gay' is.

We now have a shortlist of 3 boys - homophobe junior isn't in there.
