‘And now on to our next highlight!’ Shaun says as we all get back on the cart. He starts it up and we drive for ages past more white buildings, lawns and trees. We turn a sharp corner and we all look excitedly to see what’s next … but it’s more white buildings, lawns and trees.

I suppose I knew this is what a studio lot looked like. But I can’t help feeling it’s a bit … meh. Where are the cameras? Where’s the guy shouting ‘Action’? And, more importantly, where’s the wardrobe department? I really wish I had a map, and I really wish Shaun would stop. As if reading my mind, he pulls to a halt and turns to face us, his face glowing with professional animation.

‘Ever wondered where was the famous grating that Anna lost her ring down, in the movie Fox Tales? Right here, on the Sedgewood Studios lot! Come and take a closer look.’

Obediently we all get off the cart and have a look. Sure enough, on a nearby fence there’s a framed still from some black-and-white film of a girl in fox furs dropping a ring down a grating. To my eye, it’s just an old grating. But everyone else is taking pictures of it, jostling for a good view, so maybe I should, too. I take a couple of snaps, then edge away from the group while they’re all engrossed. I walk to the corner and squint up the road, hoping to see a sign saying Wardrobe or Costume Design, but it’s just more white buildings, lawns and trees. Nor can I see a single film star. In fact, I’m starting to doubt whether they really come here at all.

‘Ma’am?’ Out of nowhere, Shaun has appeared, looking like a special agent in his dark jacket and headset. ‘Ma’am, I need you to stay with the group.’

‘Oh right. OK.’ Reluctantly, I follow him back to the cart and get on. This is useless. I’m never going to meet Nenita Dietz, stuck on a cart.

‘To your right, you’ll see the buildings that house some of the most famous film-production companies in the world.’ Shaun is booming down the earpiece. ‘They all produce films right here on the Sedgewood lot! Now, we’re heading to the gift shop …’

I’m peering out of the cart as we trundle along, reading every sign we pass. As we pause at an intersection, I lean out, squinting, to read the signs on the buildings. Scamper Productions … AJB Films … Too Rich Too Thin Design! Oh my God, that’s her! That’s Nenita Dietz’s company! Right there in front of my eyes! OK. I’m off.

With a burst of excitement, I unbuckle my belt and start clambering off the cart, just as we start moving. The momentum sends me sprawling on to the grass, and everyone on the cart screams.

‘Oh my God!’ one woman exclaims. ‘Are these carts safe?’

‘Is she injured?’

‘I’m fine!’ I call. ‘Don’t worry, I’m fine!’ I hastily get to my feet, brush myself down and pick up my portfolio. Right. New career here I come.
