I found these at a wonderful site called Matte Shot, a tribute to golden age special effects artists. The third image shows the matte as it appears in the film, and you can see a lot more at the link, including a miniature of the castle. Took got his start at Britain’s Pinewood Studios, and his first mattes appear in Warlords of Atlantis (1978), the oft-forgotten (and still unreleased on DVD in the U.S.) fourth fantasy-adventure directed by Kevin Connor and starring Doug McClure.
Took went on to work on classics like Clash of the Titans (1981), The Adventures of Baron Munchausen (1988), and Batman (1989). More recently, he has worked as Miniature Effects Supervisor on The Wolfman (2010) and The Monuments Men (2014). He was also Visual Effects Supervisor on my favorite horror film of the last 15 years, Neil Marshall’s The Descent (2005).
2 Warps to Neptune 
Nice shout out for The Descent – that’s the first horror film in years that literally gave me chills and made me jump in my seat. Bonus: for those who play D&D, it shows you what a dungeon crawl really looks like.
Fucking great and sadly overlooked film.
Agreed. The Descent is awesome. Did you see the alternate ending on the DVD? I thought the theatrical one was fine.
Was that the happy ending?
As a reward for high test scores (or something like that, I can’t remember), my entire sixth grade class got to sit on the floor in the school gym and watch Warlords of Atlantis projected onto a sheet. It was shown along with Gus, the Disney movie about a mule that kicks footballs (!).
We watched those too. I also remember The Watcher in the Woods, The Red Balloon, Snowball Express…
