In the film A Little Chaos, Philippe is played by a suave Stanley Tucci.

In The Man in the Iron Mask, he and Louis are reimagined as twins and both played by Leonardo DiCaprio.

But my personal fave, of course, is the TV drama Versailles, shown on the BBC, which I got to discuss every week as the co-host of BBC Two's Inside Versailles with Professor Kate Williams.

Bonjour.

But was Philippe more than just King Louis' chaotic little brother?

What's it like to grow up as the spare?

And how long can you really keep a menage a trois going?

Let's find out.

Right.

Dr. Jonathan, let's start at the start.

When little Prince Philippe was born, who were his parents?

What I was going to ask, Tom, you have a brother.

If your brother had been called the God given son, how would you feel about that?

Well, I am the eldest, actually.

So you're the God-given son.

I am the God-given one.

And I was born after 10 years of my parents' pregnancy.

So I'm very similar, obviously.

Tom, why do you think it took Queen Anne and King Louis XIII 23 years to conceive?

Maybe just not into it.
