The Myers' house appears to be a huge gothic mansion, although the house appeared as a smaller Victorian house in previous films.

When Mikey is cleaning his car outside the liquor store, a set light can be seen on the hood of the car as he wipes it down.

At the end of H4, Rachel tells Jamie to "Stay right here, in the truck." In the H5 re-cap, she simply tells Jamie "I want you to stay in the car."

At the costume party, they introduce Jamie as Jamie Carruthers rather than Jamie Lloyd. She could have legally changed her name over in the past year, but assuming she didn't, it could be a flub.

When Tina is talking to Mikey (actually Michael) in the car, there's a portion of the words that don't match up with what her lips are saying.

While Michael is chasing Tina and Jamie in the car, Michael's position changes from the passenger seat to the driver seat several times.

NEW: Watch when Tina is stabbed by Michael after the car crash. The blade of the knife bends!

NEW: Watch when Jamie is in the laundry chute hiding frim Michael. During the entire laundry chute scene, sometimes she has 1 shoe, sometimes she has 2.

NEW: When Dr. Loomis is hitting Michael with a floorboard, what is all that light coming from outside?

During the end credits, when they tell the label the soundtrack is on, Varese Sarabande is misspelled as Varese Serabande.

Dr. Loomis says that his memory goes back 12 years to his burnt arm from 1978's Halloween. But, H5 takes place in 1989, which is actually only 11 years.

When Jamie goes into the attic, trying to hide from Myers, she discovers the body of Rachel sitting in a chair next to the stairs (leading out of the attic). You also see her body when Michael comes up into the attic after Jamie. When you see Jamie running down the attic stairs, you don't see Rachel's body anymore.  Her body couldn't get up and walk away.

In HALLOWEEN 4, Jamie is 7 years old, but in this installment, Tina says Jamie is a 9-year-old girl. It's tough to gain two years in age after just one year!

Look when Jamie hides in the hamper. There is a door to the left of it. When she falls down and after Michael starts beating the hamper with his knife, Jamie gets out. If you look toward your left, the door is gone.

When Mike is looking in his mirror and Michael Myers drags the fork on the back of the car, Mike soon gets out of his car with a crowbar. When Michael Myers grabs him on the neck, Mike drops the bar. Notice it fell behind him to the right -- then Michael Myers hits him in the head with the fork and Mike falls back shaking. The pitchfork is on the right of him by his upper legs.

After Sam sees her boyfriend get the pitchfork through his body, she lunges at Michael with the same pitchfork.  However, Michael grabs the pitchfork and slams her against the wall. As he slashes her with his sickle, you can see a bunch of blood splash onto his WHITE mask, but in the next scene, it is gone.

Notice Mike's car, it had no bottom lights on it if you look at it earlier in the film.  But, when Michael is chasing Tina, Jamie, and Billy if you looked there were bottom lights on the car and they were lit up in several shots.

Sam's devil horns at the party keep dissappearing and then reappearing.

When Tina is upstairs looking at herself in the mirror, she has  her jacket on.  But, when the doorbell rings and Tina runs down the stairs, she is carrying it.  When Sam scares her, SHE HAS IT ON all of a sudden!

Jamie Lloyd's cut on the front of her face at the top keeps changing sizes.

The end credits say, "In order of appearance," and then list the cast.  However, the list they have isn't actually in order of appearance.  They list Rachel, then Sheriff Meeker, then Sam Loomis, and then Jamie Lloyd.  When you view the film, you'll notice it should go Rachel (first seen in the truck), then Jamie (seen ducking under the dashboard from the H4 flashback), then Meeker (shooting Michael), and then Sam Loomis (holding Jamie after Michael falls in the mineshaft).

The address is supposed to be 45 Lampkin Lane, but the address clearly states something in triple digits (100?) when Loomis visits the house during the daytime.

On the H5 DVD, the on-set interviews say "On the Set, 1988" when the movie actually was filmed in the Spring of 1989.

Sammy's gloves are on again and off again, throughout the barn scene.

When Jamie is talking about the "Big Cookie Woman," an officer tries to get a hold of Sheriff Meeker.  Over the radio, the officer says, "Sergeant Meeker, what's your 20?"  He should have called him Sheriff, however, not Sergeant.

During the car chase scene at the Tower Farm, the different camera angles reveal more than one person occupying the car that only Michael is supposed to be driving.

Can be spotted watching the H5 DVD:  When Michael is coming down the river, as soon as he grabs onto the net and starts pulling himself up, there is something sticking out of the back of his left shoulder. It looks like it could be some kind of wire hidden under his clothes.

Can be spotted watching the H5 DVD: When Michael kills Mike with the fork, he lifts his arm to stab him and his sleeve pulls back.  You can clearly see where the dark burn makeup ends.

When Mikey is cleaning his car outside the store, Tina jumps up near the back of the car and scares him with the mask. She puts the mask over his head and he pulls it away, throwing it toward the car. As he tears it away, his glasses are still on. In the very next shot as he throws the mask into the back of the car, his glasses are gone. When he gets behind the wheel, he reaches back and retreives his glasses from the backseat.
