Trying to find Harry Enfield sketch. Help.

I'm trying to find a sketch which has, I think, Harry Enfield in it, so its maybe from Harry and Chums.

It's a sketch with Harry on a period drama film set, and during his lines he keeps making an odd noise that he thinks are normal for the scene.
Anyone have any clips of this?

I know the episode you mean I'm sure, it's a one off sketch where he plays a temperamental US actor playing the part of a British aristocrat and during the sketch he asks the director if he can change a line of dialogue to what is already scripted, which is just this guttural feline wail.

Very funny sketch. It's definitely on 'Chums' - the second series I think though I'm not 100% sure, I will have it at home for sure.

Not sure if you are still looking for the sketch but I think this is what you are looking for. Took me ages to find it as well!
