It's amazing that this film is 45 years old! (and I was sitting close to someone in the audience who remembers London looking like it did back then).
Hay Castle had gone all out to create atmosphere, with a smoke machine at the back, and wolf howls in the background as we were coming in.
There was also an added extra - they showed Michael Jackson's Thriller video first, which was great fun and got us all in the mood.
It was also great fun spotting the local locations around Hay Bluff and Crickadarn - there's even a signpost pointing to Erwood.
Then, of course, there are the London scenes, around Piccadilly Circus and Tottenham Court Road tube station, and the zoo! I'll never look at that tube station the same again!
This was the first time I'd seen the film, so I had no idea that Jenny Agutter was in it, as Nurse Alex Price who befriends the werewolf, John Woodvine as the doctor, with Brian Glover as the surly Yorkshireman in the pub, and a young Rik Mayall!
There was even an attempt to show how multicultural London was - when our main characters stop for some shopping, the little supermarket is full of people of Indian heritage.
So it was a very enjoyable evening.
Coming up soon at Hay Castle, there's Peter and the Wolf on Saturday 7th November, with music from the Solstice Collective Wind Quintet and puppeteers Jodie Yates and Eve Wilson providing the action of the story. That's at 5.30pm, with children and under 25s free, adults £15.
And for Christmas, they're doing A Child's Christmas in Wales, performed by the Lighthouse Theatre. This is a double bill of stories by Dylan Thomas (of course) and also Richard Burton. It's on Friday 18th December at 7pm. Tickets are £14, and £8 for under 16s.
