Presuming Ed
Even though Eddie Tagoe's role as Presuming Ed in Withnail and I was one of the smallest parts, we get more searches for him than any of the other supporting characters including Farmer Parkin, The General or Miss Blennerhasset.
If you believe everything you read on Eddie Tagoe's Wikipedia entry, despite a few other bit-parts in films like Raiders of the Lost Ark, he has since given up his acting career and returned to reflexology.
