Phantasm I-IV plot explanations **SPOILERS**
This board needs a thread where fans can discuss the Phantasm plot. Phantasm III and IV convolute the story and so I'm most interested in hearing from those who have seen and think they understand the developments in these movies. Here's my brief take on what the hell is going on in Phantasm I-IV.
Just as there are many dimensions, there are many Mikes and many Tall Men. Due to some cosmic connection, whenever a Tall Man meets a Mike, he pursues him in an effort to create a successor. At the end of Phantasm III, he tells Mike that he needs to realize his destiny. Also keep in mind that Tall Man never exhibits any interest in killing Mike; he simply trys to capture and convert him. In a flashback sequence in Phantasm IV, Mike and Jody hang the Tall Man. Mike inexplicably goes back and frees him and the Tall Man doesn't hurt/kill him upon release. Also in Phantasm IV, remember that Reggie has a vision of Mike as a Tall Man. These scenes seem to suggest that, throughout time and dimensions, Mike is a figure who is chosen to be the next Tall Man.
Phantasm IV includes a flashback to the Civil War where Tall Man is operating on the head of an adult Mike (presumably implanting a ball into his head). This can not be the same Mike who appears as a child in the original Phantasm. The flashback just shows that the Tall Man and Mike figures are connected through all time, space, and dimensions. When Tall Man encounters the young Mike in the original Phantasm, Tall Man knows that this boy is the one to become the next Tall Man. He finally captures this Mike in Phantasm III and implants the ball into his head, beginning Mike's "transformation" (as its specifically called by Mike in the beginning of IV) into a Tall Man. This is just one more instance of a Tall Man finding a Mike, implanting a ball in his head, and creating a successor.
How does this sound to you? Please feel free to prove me wrong. I'm anxious to hear people explain these great movies. Well, I'm anxious to hear from anyone except for that jackass, bleeder.
