Simpsonai Treehouse of Horror II (1989– ) watch online HD

Al Jean pitched the idea of having "scary names" in the opening credits, inspired by old issues of EC Comics..

The Monkey's Paw segment is based on a short story written by W.W. Jacobs at the start of the 20th century.

The segment involving Bart as a boy with the power to make anything happen just by using his mind is based off The Twilight Zone: It's a Good Life (1961), itself based off the 1953 short story of the same name by Jerome Bixby.

This was the first Treehouse of Horror episode to have actually been broadcast on Halloween. This would not happen again until Simpsonid: Treehouse of Horror X (1999) in Season 11.

Mr. Burns hums a little of "If I Only Had a Brain" while removing Homer's brain.

In production order, this was the first Simpsonid (1989) episode to be animated by Anivision, which was the first non-AKOM overseas studio to work on the show.

Bart's Nightmare, the second segment, was based on The Twilight Zone: It's a Good Life (1961). That episode was remade and used as a segment of Twilight Zone: The Movie (1983). That segment starred Nancy Cartwright, who is the voice of Bart

One of the writers who created the Davy Crockett joke thought it was so funny that he actually mimicked the actions of Mr. Burns putting on Homer's brain in the writing room; the producers thought that it was hilarious, so they decided to add it into the episode.

When Kang and Kodos's ship lands on the Statue of Jebediah Springfield, the statue's head falls off as the rest of the statue falls over, as a reference to Simpsonid: The Telltale Head (1990).

There was a debate about whether to include Kang and Kodos in all Halloween specials after the episode; eventually, the writers agreed to make it a tradition.

While writing "The Monkey's Paw", Sam Simon, one of the writers, wanted the fingers to go down in such an order so they would eventually have the middle finger sticking up. Once the animation would have been complete, however, they could not have gone through; Fox would have refused to air the episode. They had considered the alternative of deliberately blurring the middle finger themselves, but decided that Fox would have also refused.

When the Moroccan salesman tries to warn Homer Simpson, saying "You'll be sorry", the animators forgot to move his lips. They only realized their error after the broadcast, so they decided not to change it.

For this episode, there were a lot of loop lines; for instance, the ending to "The Monkey's Paw" was added to the last second. As a result of the loop, they still retained Flanders's old house next to his newly created castle. In order to make the episode fill the time needed, the animators often extended the laughing time for Kang and Kodos.

According to George Meyer, the animation for when Bart sits up, screaming, was extremely tough, especially to make the mouthlines natural.

During the beginning of the segment "The Monkey's Paw", Hank Azaria faked some Arabic.

Though it took a long time, the design of the monster version of Snowball II by John Rice was greatly enjoyed by the producers, who thought it looked "just hideous, just right".

Bart's prank call to Moe was thought of by John Swartzwelder, one of the writers; however, Hank Azaria detested the line.

When Burns and Smithers go to the lab, the animators decided to make the animation a bit more impressive, and decided to do the concave and convex images of Burns and Smithers. Even though it was tough and took up more time, the producers felt that it was a necessary tour-de-force.

Originally, Homer's robotic voice was done post-animation in order to avoid stress on Dan Castellaneta.

The scene where Marge gives her warning to the audience is similar to the her warning in Simpsonid: Treehouse of Horror (1990), but with different dialogue.

This is the only Treehouse of Horror episode where titles of the segments don't appear in.

According to Jim Reardon, the ending to "The Monkey's Paw", where Flanders got a castle, was a last minute edition.

So far the only Treehouse of Horror episode with no deaths (unless one counts Mr. Burns's head being separated and placed onto Homer's head as a death).

At the end of the credits the Gracie Films logo in a Halloween special does not have the scream, but have the organ.

The credits and font is the same as Simpsonid: Treehouse of Horror (1990), but have different notices.

In the opening a group of trick or treaters walk by wearing sheets. They are all dressed in the same costumes the Peanuts characters wear in "It's the Great Pumpkin Charlie Brown".
