Harry Peacock says he would last about a week if he were marooned on a desert island for real.

Can you explain High & Dry to us in one sentence?

Imagine getting into a lift at Gatwick airport with four people you would never really come across in your day to day life. Now imagine being stuck with them.

You play Douglas - how would you describe him?

Conservative, really doesn't like change, but a good man just trying to put his best foot forward.

Is it fair to say he's the most cautious of the bunch?

Certainly.

Had you worked with any of the cast before?

I'd shot the blap [pilot episode] with Asim and Marc, and I've also made a pilot with Vicki which she'd written called Grey Dogs which was brilliant.

I met Marc doing Drunk Histories. But I previously knew him because he'd played my wife's husband in an Alan Ackybourn play.

I hadn't worked with or met Grace but she was a delightful addition to the team. Everyone really made me laugh... which was nice.

Filming in the Seychelles seems pretty idyllic. Was it as luxurious as it looked?

I was almost embarrassed about telling people where we were making it because it's such a famously idyllic tropical location, but filming is filming whether you're in Croydon or the Seychelles.

We had waves crashing in dragging us out and it was extremely hot - we had to fit a lot in every day. But the boat to and from the location every day was magical.

Ever come across a Brett Sullivan type character on a plane before?

No not really, but Marc based Brett on an experience he had with a flight attendant.

You play Ray Purchase in Toast Of London. How do you think he would have fared being marooned on a desert island?

Ray would have gone to a very dark place.

Were you a fan of Marc Wootton's comedy before High & Dry?

I adore Mr Poppy.

Marc's character Brett takes a bit of a shine to Douglas. He's quite an acquired taste! How do you think he handles the attention?

Brett and Douglas go on a real rollercoaster with their relationship. From Douglas's point of view, initially he's sympathetic towards Brett then quite scared. But they end up needing each other.

How do you think you would fare, marooned on a desert island?

I suppose I'd last about a week?

If not you, which of the cast would fare best, and why?

I don't think any of us would last for more than five days.

If you could only take one comfort to a desert island with you, what would it be?
