not Brian Sewell
I figured it out, for so long I had been thinking it was Brial Sewell who played Harry, but in fact it was James Fox (http://www.imdb.com/name/nm0289038/). But you've got admit, I wasn't far wrong.
Brian was really hard to find as well because I was sure he did reviews for a rag, but I couldn't find anything and now I've checked his Wikipedia profile I feel even more confused as it doesn't list him as belonging to a paper.
