This shot features two of Ron Cobb's better known alien designs. Lurking in the shadows is the Gotal, Feltipern Trevagg. Although no production nickname for this alien has been revealed, a 1989 West End Games miniature set identified him as "Kerru."
Across from him sits the peaceful Ithorian, Momaw Nadon. As we all remember from the vintage toyline, Nadon's production nickname is "Hammerhead." Ithorians have unique vocal patterns since they have two mouths -- one on each side of their flowing neck.
Barely visible in the background is Trinto Duaba, or "Terminal Man."
He is from a rare species of Force-sensitive shapeshifters called the Stennes.
How exactly did Wuher manage to get IG-88's head in his bar?
The scuffle arouses attention from the peanut gallery. The Saurin masks used for Hrchek and Saitorr would be re-used in Return of the Jedi for one of Jabba's cronies.
Note that Rycar being a Bimm matches West End Games' description of the species, and not Dark Horse's.
According to the script, the aliens that accost Luke are "a large, multiple eyed creature [that] gives Luke a rough shove" (Ponda Baba), "a short, grubby Human" (Dr. Evazan) and "an even smaller rodent-like beast." Does this last sound like Kabe to you? If you watch the bar shots, Evazan appears to talk to Kabe. When Kenobi cuts off Ponda’s arm, you can distinctly hear his deep roar/scream, Evazan’s grunt, and a third, whiny moan-squeal. According to the script, the creature (Baba) is "cut from chin to groin" and the rodent is "cut in two."
In the background of this shot is Kitik Keed'kak (or "Praying Mantis"). This powerful female Yam'rii was performed by Jack Purvis, who played the Jawa Chief ("Dathcha"), the Ugnaught Chief ("Ugloste") and the Ewok hunter, Teebo.
Galaxy Guide 7 calls them Chachi and Ohwun De Maal. The Screen Saver package calls them Bringe and Probos. The card game calls them Ellorrs Madak and Baniss Keeg. Their production nickname was "Goggle Eyes".
The severing of Baba's arm was originally achieved in one shot (as opposed to a cut-away of the arm on the floor). If the shaky hand-held footage of this shot were to continue, you would see Baba's arm drop on the floor. Interestingly enough, it is his left arm that gets severed in this take. You can barely see it in freeze-frame. If you have the Behind the Magic CD-ROM, you can see this full shot.
Rather than do it in one take, the severing of Baba's hand was acheived as a cut-away insert. However, a production mix-up ended up with not only the wrong type of hand (fingered and hairy instead of smooth and finned) but also the wrong arm! (right instead of left).
A Rodian, possibly Greedo, seems rather impressed with Obi-Wan's handiwork. There at least three Rodians in the cantina. One is named Thuku.
After Ponda’s arm is severed, there is a shot of the bar bystanders turning to look and turning away. This shot is the same as one several cuts ago, but it is reversed. This occurs when an editor or director purposely or accidentally flips the negative to change the image left to right.
Star Wars has a lot of these reversed shots, which always struck me as odd since almost nothing in Star Wars is symmetrical. Look at costumes such as Vader, Chewie, Threepio, Stormtroopers, and Artoo. They all have something (Vader’s chestplate, Chewie’s bandoleer, Threepio’s legs, a stormtrooper’s knee-pads, and Artoo’s anatomy) that keeps them from being shown backwards.
