We can reveal the name of another character actor in FOTR: Noel Appleby.
I happened to be talking to Kiwi actor Noel Appleby recently, and it turns out that he played a character called Everard Proudfoot in the opening Shire scenes. The name confused me at first – there’s an Everard Took mentioned in the book, but the only Proudfoot we know of is Odo. Nevertheless, Noel Appleby’s line was to shout out “ProudFEET!” as per the scene at Bilbo’s party.
Noel’s is one of those familiar faces in Kiwi film – I remembered him playing Ulf in Vincent Ward’s The Navigator, in which role he was awarded Best Supporting Actor
