The BAFTA-nominated producer of "Lost in La Mancha" discusses the unmaking of Terry Gilliam's "The Man Who Killed Don Quixote".

At what point when you were filming the making of "The Man Who Killed Don Quixote", did you realise you had a movie?

We didn't. We didn't know that until quite some time after they [directors Keith Fulton and Louis Pepe] finished shooting. Because they got back from Spain in October of 2000 and it took until the end of January to assess all of the material, because everything had to be watched. And then Keith and Lou assembled a series of scenes which we all had a look at. It wasn't until February or March that they decided that they had the material to make it into a feature.

Were you worried about how Terry Gilliam would react to the film?

Terry is candid, open and honest and his whole ethos in life is warts n' all. He wouldn't have any respect for you if you didn't tell him the truth.

How have those involved coped with watching it?

As recently as last week I was talking to Tony Grisoni [co-writer on "Don Quixote"] and he said it still pains him, if he has to look at it, which he has. We've made him come to all sorts of events. The film was shown in Los Angeles at a special event a while back. It takes him a week to ten days to recover from sitting and viewing it over again.

"Lost in La Mancha" is now out to buy on DVD.
