In Star Wars VI: Return of the Jedi Luke Skywalker is captured by Jabba the Hutt and taken to the Sea of Dune to be thrown into the Pit of Carkoon to be digested over a thousand years.
In Jabba's court he is brought in front of Jabba with his hands handcuffed behind him. After a brief conversation where Luke tells Jabba he should have negotiated the scene ends and cuts to Luke, Han Solo, and Chewbacca all on a ship heading to the Pit of Carkoon.
C3PO: "You will, therefore, be taken to the Dune Sea and cast into the Pit of Carkoon, the nesting place of the all powerful Sarlacc."
When they arrive at the pit Jabba offers to let the trio beg for their lives. Luke is still on the ship with his hands tied behind his back.
As he walks out on the plank his hands are miraculously no longer cuffed. He has his hands at his sides. It appears at this point Chewbacca and Han Solo who were also cuffed are also no longer cuffed.
Luke jumps off the plank, grabs the plank with his hands, flips up, grabs the light saber flipped to him by R2D2 and pandemonium ensues.
How did Luke's hands get freed? Why would somebody take the cuffs off of him?
