lovatts big december

Hi eala

Welcome to a2k, you we'll find plenty of people here who will help you with your queries.
Before I answer your question a few tips should you post again in the future.
Whenever you post a puzzle question, provide as much information as you can, a lot of people (overseas) do not know of Lovatts and their magazines, so wouldn't have a clue what puzzles you are referring to.
In your case it would have assisted to say, for 140a Film buff, the word consists of 8 letters, and include any letters you may have already found like this "c?n?a?te", and also mention from "The Demon"
The same goes for 121d Violin bow resin, the word consists of 5 letters and I have the following, "r?s?n"
It also pays to read previous puzzle postings, as you often find your questions may already have been raised and answered. In your case 140a popped up within the last few days
The answers you require are:
140a = cineaste and 121d = rosin

Hope this helps, good luck with your entry.
