By sheer coincidence, a young boy dressed as a clown can be seen at the beginning to the left of the Myer's House. He is also seen later dragging his sister to Michael Myers, asking him to kill her. This is very similar to the plot of the 1978 Halloween.
The reason why Laurie's house is shown so little in this documentary is because while filming there, nothing really happened. The "action" according to the director is much greater at the Myer's House and Halloween Hedge. This is because they are much easier to find on Google Maps. You can simply type these names, as opposed to actually knowing the physical addresses.
Robert Price was featured in Like Michael: A Halloween Fan Documentary without his mask on; albeit wearing sunglasses .
The director saw the movie as a "nature film". He had filmed in South Pasadena in previous years on Halloween and knew what to expect. He simply miced up his actors with a wireless lav and filmed a fair distance away using a long lens. He even opted out of using lights, as this would affect how the trick-or-treators reacted to Michael Myer's presence.
Robert Price is actually wearing two masks. The H1 William Shatner modified mask as well as a black satin mask to give him, as Dr. Loomis described MM, "the blackest eyes." Toward the end of shooting, Robert removed the second mask to avoid overheating.
