One curious aspect of the Thriller segment in This Is It is the never before seen use of a Black Widow Spider. Michael Jackson emerges from the paralyzing clutches of the Black Widow unharmed (start at :22 of the video below).
However close inspection of this Black Widow shows that it's design is like no other Black Widow I have seen:
Interestingly enough, after he walks out of the spider, and takes a look around to the left and right (making sure the coast is clear?), MJ strikes a similar "mummy-like" pose:
Then still looking at the camera he indicates he is ready to fight:
And finally..the scare!
These three moves happen in about a second before the scene switches.
So was a metaphorical spider holding the "mummy" until it was able to emerge?
UPDATE: Seeing Clues blog reader "Cristadobre" sent me the below vintage Disney short film "Egyptian Melodies" which contains a segment where a spider brings mummies to life:
