This download is the only extract the BBC has of this edition of desert island discs. The presenter was Roy Plumley.

Now, carry-on sergeant, the first carry-on film, it didn't cost much money, did it? No. But it made a bomb. Yes. And you made some more?

I didn't, I made the same one again.

Well, you said that, I did. Yes, I did. And after two or three carry-on films, you bought your own studio.

You have virtually a repatriate company playing in these films. Yes. Yes. Two years. Yes. That's a reason for that.

Yes. They are timed because the artists in the carry-ons are either in pantomime or a summer show.

And so the films have to be made between the two. Yes. And have they all have the same director? Yes, Gerald Thomas. Yes.

And the same writer? Yes. Thomas Rothman? Yes. Bless his heart. What's your theory about the comedy that you use?

You use the same jokes over and over again. But they weren't new when you first started using them. Neither is the audience.

Is it familiarity, the reassurance of familiarity, what is it? Well, I don't know. You know, if I kept a sweet shop,

and someone came in every week for licorice all sorts, they said, don't have those. They have these fancy chocolates from France or Belgium or somewhere.

And they took them away. They wouldn't come back again. They'd go somewhere else for the licorice all sorts, but they'd still want licorice all sorts.

I think if people what they want, they're always true, you know, indeed. Very nice people of the public. Very loyal indeed.

Carry on has moved into the theatre now. Yes. It shouldn't be a surprise to anybody. It's something I've wanted to do for a long time,

and I thought I will wait until I've made 25, if I ever make 25. It's something about 25,

but the silver wedding, isn't it, or something? Well, they are surely self-perpetuating,

but I know you can go on to 125 with confidence.
