WILHELM SCREAM: heard when one of the Pykes is catapulted into the air just outside the fortress prison.
The droid which tortures Trace and Rafa is a Roche Hive 8D smelter droid model, similar to 8D8, who was seen torturing a GNK droid in Jabba the Hutt's palace on Tatooine in Star Wars: Episode VI - Return of the Jedi (1983).
The Ithorian alien that Trace helps free from his cell while trying to escape, is dressed the same as the original "Hammerhead" Kenner action figure that came out in 1977, which is based on an alien of the same species in the Cantina in Star Wars Episode IV: A New Hope.
