Dante's Peak (1997) Poster

(1997)

Goofs

Audio/visual unsynchronised 

In the establishing shot of the grandmother's cabin, we hear a chorus of peeping in the sound effects mix. These are small frogs often called "spring peepers" and they will usually only sing after sunset, not in the middle of the day as depicted here.

Doctor Dalton reports that there is enough carbon dioxide coming out of the ground to kill trees and wildlife. While this is true for animals (which would suffocate), trees and other plants would thrive in heightened carbon dioxide levels. He means sulfur dioxide, which is toxic to both plants and animals and would account for the increased acidity in the water.

In the bar scene, the night before Harry and the gang are to depart Dante's Peak, Paul walks up behind Rachel and Harry and calls Rachel by her real name Linda. (in the VHS version)

The one-lane bridge leading out of town is wide enough to fit two cars side-by-side during the evacuation, yet when the vulcanologists are fleeing in the Humvees and USGS van later, it is barely wide enough for one vehicle.

Ruth is badly burned when she swims a short distance across the acidic lake, but Harry seems unaffected despite rowing with his coat-covered hand for about five minutes.

The helicopter crashes into the ground nose-down and continues moving for several feet after impact, which should indicate that the cabin is being crushed; we also see parts flying off the rotor. But a moment later, it rises again in a manner completely unlike the way the wreckage might bounce, more the way it would if was still under power; and we see that the cabin is still intact.

After Harry, the Mayor and her kids drive into the mining tunnel to escape the eruption, they walk deeper into the tunnel to the kids hideout. When Harry goes back to the truck there's a collapse blocking several feet of tunnel between Harry and the Mayor and kids. During the rescue Harry comes out, they pull the truck out and then a couple minutes later the Mayor and kids come out without the tunnel collapse being cleared.

When the volcano had started erupting, Harry and Rachel rushed back to her place in his truck to get her kids. The both of them run into her house and she found the letter from the kids. They run back out to the truck and the truck's headlights are on. They're standard headlights, which appear yellow in color. They leave and find the bridge is jammed with traffic and Harry decides to cross the river. In the shot of them crossing the road and going down the bank towards the river, not only are all the truck's lights on - not just the headlights - but they're very bright, white, possibly HID headlights until the truck's demise.

When the crew is unloading SpiderLegs in the parking lot, Greg has a highly noticeable case of five o'clock shadow. Less than a minute later, when he is inside directing SpiderLegs remotely, he is clean-shaven.

After Terry gets crushed by Spiderlegs, Harry starts heading down to help Terry. He rappels down about 20 or 30 feet. In the next scene, he is back at the top of the crater preparing to come down.

The red van that Paul is driving onto the bridge when they are evacuating the town has no vent windows, yet when Paul is stuck on the bridge, and it begins to overturn, the same van that he was driving can be seen to have vent windows.

Factual errors 

When Harry drives the green pick-up truck over the thinly crusted lava flow, the truck comes off the flow with nothing more than four flat tires and a charred bottom. In reality, lava is capable of temperatures as high as 2,000 degrees Fahrenheit, which would have melted the undercarriage and left them trapped.
In one of the scenes, the pick-up truck was trying to outrun the pyroclastic cloud. A pyroclastic cloud moves at up to 700 km/h (450 mph) and could not possibly be outrun by a truck with no tires.

Cascade Range volcanoes do not typically erupt flowing basaltic (free-flowing) lava. They certainly do not simultaneously erupt pyroclastic and basaltic flows as depicted.

The boat engine was water-cooled by taking in water from the lake and running it through the engine. The acid in the lake would have caused the engine to seize very quickly.

Though, it is true that volcanic activity can turn lakes and other bodies of water around the volcano acidic. But, the acid would not burn through the boat as quickly as depicted in the movie.

Pyroclastic ash is made of tiny particles of volcanic glass. In reality this would have scratched the windscreen of the pick-up when the wipers were on.

After the eruption (following the meeting in the school) we see many broken cables flowing around. In reality, that would have short circuited the town's electrical system and the whole town would have gone dark.

Miscellaneous 

When the on-ramp collapses, several vehicles are seen from the right hand side falling off and nobody is in the vehicle (not even dummies).

At the end, the rescue crew removed Harry Dalton from the vehicle wreckage then pull out the wrecked vehicle and go in for the Mayor and her two children. In Harry's injured state with the bone protruding from his elbow in such a way, it would have made more sense to remove the vehicle from the entrance, then remove Harry from the wreckage and cause as little pain as possible to Harry. Not to mention the fact his colleagues throw their arms round him and he forgets to wince as if he wasn't injured.

When Harry is rescued from the mine, a blanket is wrapped around him. As he walks towards the mine where Rachel and the children are being rescued the blanket clearly slides off. The next scene shows Harry still wrapped in the blanket.

Incorrectly regarded as goofs 

When Harry and Terry are measuring the concentration of sulfur dioxide in the caldera, the instrument probe is protruding out the open cabin door into the helicopter down wash. Sulfur dioxide is more than twice as dense as air; it may seem highly unlikely that this technique would provide any meaningful results, but the instrument that Harry and Terry are using is a Barrington Correlation Spectrometer (COSPEC), which measures SO2 concentration by comparing the difference in UV spectrum seen by the instrument to a known value. Therefore, the depicted use of the instrument is correct, and is in fact the same way volcanologists measured SO2 levels prior to the Mt. Pinatubo eruption in 1991.

When they go to save the grandmother, just before the lava comes bursting through the wall, the grandmother has a garbage bag in her hands. When the lava breaks through, she appears to drop the bag and starts running. Then they show the whole family outside, and the bag is back in the grandmother's hands, with no time for her to have picked it up. In fact it was Mayor Wando who dropped her bag; she was standing in front of the grandmother, making it appear that she dropped hers.

A station wagon, an Olsdmobile Cutlass Cruiser, is clipped by a black Chrysler while trying to enter the freeway on-ramp. When the on-ramp collapses, several vehicles behind or beside the wagon are seen further ahead, and the wagon has disappeared. Most of those vehicles, like the Chrysler, forced their way ahead, and others are only similar to other cars near the wagon.

A red Ford Escort hatchback is parked outside the high school. A red Ford Tempo sedan is later seen driving onto the on-ramp. A third, unidentifiable, red car is seen actually on the on-ramp just as it collapses. All three are different vehicles.

Plot holes 

Much is made of the fact that the one-lane bridge and the freeway are the only two ways in and out of Dante's Peak, and that upon the collapse of both, Harry, Rachel and the children are stranded. However only one on-ramp is ever seen to collapse, and despite a section of the freeway collapsing as well, nobody ever checks to see if the off-ramp (and most likely, an off-ramp and on-ramp on the opposite side for the other direction) is still standing and accessible. Even with the small section of freeway down, this is a clear escape route despite potentially traveling on the wrong side of the road for miles.

Revealing mistakes 

No one removed any Ruth's supposedly acid soaked clothing after she got out of the lake so she would continue to be burned by the acid.
Tremors strong enough to reduce buildings to rubble hit the town, but the trees lining the sidewalk remain motionless.

When the freeway collapses, all of the vehicles very obviously have no occupants. This is because all the cars are in reality scale models, which are used several times to film stunts without using CGI.

When part of the freeway collapses, cars on the section still standing do not move, for no reason.
