I don't know that I'm aware of enough entries in this category to even consider it one, but I'm a sucker for the union of political and film satire as embodied in alternate film commentaries.

I was reminded of it when seeing The People's History of Tattooine which was first one of those spontaneous, emergent forms of Twitter humor that always brightens that otherwise dystopic landscape.

What if Mos Eisley wasn’t really that wretched and it was just Obi Wan being racist again?

TIM CARMODY
What do you mean, “these blaster marks are too precise to be made by Sand People?” Who talks like that?

JACOB HARRIS
also Sand People is not the preferred nomenclature.

TIM CARMODY
They have a rich cultural history that’s led them to survive and thrive under spectacularly awful conditions.

JACOB HARRIS
Mos Eisley may not look like much but it’s a a bedroom community with decent schools and affordable housing.

TIM CARMODY
You can just imagine Obi-Wan after years of being a Jedi on Coruscant being stuck in this place and just getting madder and madder.

JACOB HARRIS
yeah nobody cares that the blue milk is so much more artisanal on Coruscant

TIM CARMODY
Obi-Wan only goes to Mos Eisley once every three months to get drunk and he basically becomes like Byron.

Years ago, I laughed at UNUSED AUDIO COMMENTARY BY HOWARD ZINN AND NOAM CHOMSKY, RECORDED SUMMER 2002 FOR THE FELLOWSHIP OF THE RING (PLATINUM SERIES EXTENDED EDITION) DVD, PART ONE (here is part 2, and here are all four of the parts of their commentary for Return of the King).

CHOMSKY: And here comes Bilbo Baggins. Now, this is, to my mind, where the story begins to reveal its deeper truths. In the books we learn that Saruman was spying on Gandalf for years. And he wondered why Gandalf was traveling so incessantly to the Shire. As Tolkien later establishes, the Shire’s surfeit of pipe-weed is one of the major reasons for Gandalf’s continued visits.

ZINN: You view the conflict as being primarily about pipe-weed, do you not?

CHOMSKY: Well, what we see here, in Hobbiton, farmers tilling crops. The thing to remember is that the crop they are tilling is, in fact, pipe-weed, an addictive drug transported and sold throughout Middle Earth for great profit.

ZINN: This is absolutely established in the books. Pipe-weed is something all the Hobbits abuse. Gandalf is smoking it constantly. You are correct when you point out that Middle Earth depends on pipe-weed in some crucial sense, but I think you may be overstating its importance. Clearly the war is not based only on the Shire’s pipe-weed. Rohan and Gondor’s unceasing hunger for war is a larger culprit, I would say.

CHOMSKY: But without the pipe-weed, Middle Earth would fall apart. Saruman is trying to break up Gandalf’s pipe-weed ring. He’s trying to divert it.

ZINN: Well, you know, it would be manifestly difficult to believe in magic rings unless everyone was high on pipe-weed. So it is in Gandalf’s interest to keep Middle Earth hooked.

CHOMSKY: How do you think these wizards build gigantic towers and mighty fortresses? Where do they get the money? Keep in mind that I do not especially regard anyone, Saruman included, as an agent for progressivism. But obviously the pipe-weed operation that exists is the dominant influence in Middle Earth. It’s not some ludicrous magical ring.

A bit more, because I can't help myself:

ZINN: Right. And here we receive our first glimpse of the supposedly dreadful Mordor, which actually looks like a fairly functioning place.

CHOMSKY: This type of city is most likely the best the Orcs can do if all they have are cliffs to grow on. It’s very impressive, in that sense.

ZINN: Especially considering the economic sanctions no doubt faced by Mordor. They must be dreadful. We see now that the Black Riders have been released, and they’re going after Frodo. The Black Riders. Of course they’re black. Everything evil is always black. And later Gandalf the Grey becomes Gandalf the White. Have you noticed that?

CHOMSKY: The most simplistic color symbolism.

ZINN: And the writing on the ring, we learn here, is Orcish — the so-called “black speech.” Orcish is evidently some spoliation of the language spoken in Rohan. This is what Tolkien says.

Somewhat related is this, The Passion of the Christ: Blooper Reel.

Christ, shackled to a stone, is being scourged by Roman soldiers. Blood runs down his gory back. His pain is palpable.

Jesus: [writhes in pain, hands shaking]

[Cell phone rings.]

Jesus: [hands shake furiously]

[Cell phone rings. Caviezel looks up, sheepish.]

Roman soldier: Jim? That you?

Jesus: Yeah.

[Cell phone rings.]

Soldier: Want me to get it?

Jesus: Yeah.

[Roman soldier gingerly reaches into Caviezel’s blood-soaked loincloth, pulls out phone and opens it, then holds the phone to Caviezel’s ear.]

Off Camera: [laughter]

Jesus: Hey, Mom.

Are there more in this genre? If so, please share!
