Other mistake: The shape of the crystal shard is all wrong. In a flashback scene a urSkek is seen "shattering" the original, pure crystal by hitting it with a rod on one of the crystal's flat surfaces. For argument's sake we will say that in their universe it would be possible for this to create a spear-shaped hole in the crystal. However, the top of the shard is a rounded surface; it should have a flat, slanted top to match the top of the hole it came out of. Could pieces have broken off the top of the shard to give it the rounded shape? If that were true the final solution would not have worked; only the whole, pure crystal would restore the urSkeks.

Visible crew/equipment: During the landstrider sequence, before they reach the Crystal castle, you can just make out in one shot, the safety wire attached to the performer as he runs. (DVD extras says the landstrider performers had these wires all the time but this is the only time you see them).
Narrator: Another world, another time, in the age of wonder. A thousand years ago, this land was green and good - until the Crystal cracked. For a single piece was lost; a shard of the Crystal. Then strife began, and two new races appeared: the cruel Skeksis, the gentle Mystics. Here in the castle of the Crystal, the Skeksis took control. Now the Skeksis gather in the sacred chamber, where the Crystal hangs above a shaft of air and fire. The Skeksis with their hard and twisted bodies, their harsh and twisted wills. For a thousand years they have ruled, but now there are only ten. A dying race, ruled by a dying emperor, imprisoned within themselves in a dying land. Today, once more, they gather at the Crystal as the first sun climbs to its peak. For this is the way of the Skeksis. As they ravaged the land, so too they learned to draw new life from the sun. Today, once more, they will replenish themselves, cheat death again, through the power of their source, their treasure, their fate - the Dark Crystal.
Trivia: The Garthim costumes were so heavy and hard to get in and out of that oftentimes the costumed actors were suspended on a rig to allow them to take breaks between takes according to The Making Of The Dark Crystal Feature on the DVD.
Question: I believe I read somewhere that the worlds are connected by crystals and travel is possible. Is this true and where might I look for the answer?
