I have begun building the exterior set for the throne room film. Creatures have to fly in and attack a castle. The set will be about 5 feet square and will be too big to bring inside. I will place the set on the ground when ready to film and film it at night to reduce the flicker.
I took an old door and placed styrofoam pieces to form the basis of the mountain. Paper mache was placed over the styrofoam and then painted.
The bridge and a tower.
Instead of plaster of paris I used tile mortar, it is super strong and cheap, you just need to wear gloves since the mortar can burn your skin. Just mix it up kinda runny, and dip your newspaper in it just like regular paper mache.
The castle is mostly foam with paper cutouts for windows and a plastic screen cut for the top railing.
I have added another section on this side of the existing foam to extend the landscape more on this side. Photos of that later.
Go ahead, make a mess, have some fun.
