The Zorgons

Director Jon Favreau wanted to maintain a generally physical vibe for Zathura‘s special effects — aesthetically, they would also have to homage pulp science fiction from the 1950s and 1960s. The Zorgons — the reptilian creatures that invade the children’s house — were no exception. As with other character effects for the film, they brought to the screen by Stan Winston Studio. Based on vague references in the script of “green scaly space pirates”, concept artists at Winston Studio — including lead artist Joey Orosco — extrapolated an organic creature design that combined humanoid characteristics with anatomical traits and textures from various species of reptiles.

While initial concepts portrayed the creatures as more upright, the final Zorgons are hunched and bulky, with a scaly skin inspired by lizards and iguanas. Their heads house double rows of teeth — with external crocodilian interlocking teeth and internal lizard-like teeth; their necks display an iguana-like dewlap lined with thorns, whereas their eyes were based on eagle eyes. The general humanoid outline of the creatures allowed them to be sculpted and constructed as body suits for performers to wear. The suits were sculpted by Christopher Swift, Hiroshi Katagiri, Joey Orosco, and painted by a team led by Swift. The Zorgons’ skin was cast in foam latex, with fiberglass teeth — whereas their armour was sculpted and die-cast separately from the main body.

The suit performers chosen for the roles were Derek Mears (as the lead Zorgon), Douglas Tait, Joe Bucaro, and Jeff Wolfe. Following a concept devised by Favreau himself, the three suits built by the crew employed a hybrid approach: to accommodate the hunched proportions of the creatures, the performers’ heads and necks protruded from between the Zorgons’ shoulder blades. By wearing a bluescreen hood, the performers’ heads and necks could be erased in post-production. By using this expedient, the fact the Zorgons were performers in suits was better concealed and helped towards their realism.

Zorgon heads were built both as stunt, lightweight versions, and as fully-mechanized hero animatronic heads, with organic motion of eyes, jaws, tongue and subtle jugular movement. The heads and necks were mounted on the performers’ chests. Leg extensions allowed portrayal of the creatures’ digitigrade legs, whereas the tails featured internal spring mechanisms that allowed them to shake organically during the performance.

In our interview, performer Douglas Tait recalled the difficulty of shooting the scenes with the Zorgons: “they wanted us to walk in a squatted position, and with the heavy weight it was very difficult. The design was brilliant — the weight was spread out — the head weighed 60 pounds and was mounted onto my chest, and the tail weighed 60 pounds and was attached to my lower back. My head was exposed and was covered with a blue nylon stocking then removed in post. The head and tail were full of animatronics and the build looked so neat when in motion. After about five minutes in a squatted position, my legs would start shaking and I could not wait until Jon Favreau yelled cut. Also, the tail would whip back and forth so it would take you off balance when you weren’t prepared for it. In the scene where we are chasing the kid, they had us rigged on a wire to take some of the weight off while we were running.”

The digital enhancements and corrections of the suits were provided by Sony Imageworks. Most of the times the suits were shot in low lighting and angles that allowed most of the area that would be erased in post-production to be obscured either by shadows or by the creatures’ actual heads; in the few shots that needed to show that portion, a digital version of it was devised and rotoscoped in. “Sometimes parts of the Zorgon or his armour would be obscured by the head, so they’d have to restore that digitally,” said visual effects supervisor Joe Bauer.

Digital eye blinks and nictitating membranes, as well as flickering tongues were added to certain shots. In one shot, a Zorgon reveals a chameleon-like tongue; it was physically built and shot by Winston Studio as reference for the digital team, which then composited a digital tongue into the shot. “There is one tongue shot where the Zorgon flicks his tongue out like a frog catching a fly,” Bauer related. “The tongue flies all the way across the room and hits one of the kids in the back of the head. Stan Winston Studio made that as a prop that we shot as reference; then Imageworks replaced it with a CG tongue.” For the shot of the Zorgons fleeing the house, digital duplicates of the suits were animated and composited into the plates by CafeFX.
