Well, for something as huge as Grond, it's gonna take some hefty monsters to haul that thing around!
I didn't have as many reference photos as I do today, so I had to make my own monsters in my own vision.
At the time, I really liked the dinosaurs from the VOID sci-fi game, of the Viridians faction. These two monsters were sculpted to look similar to those. As usual, sculpey was used to make them.
I think the actual Grond in the movies was pulled by 3 monsters, but I only had space for 2.
They had to be completely sculpted and painted prior to attachment to the main display base.
These views will give you a better idea on the scale of the dinos!
I used some twine to make the ropes attaching the yokes on the beasts to the frame of Grond.
Tonight's late night post will show the converted Trolls... Stay tuned!
