The opening nine-minute sequence from "Pilot, Part 1" had approximately 100 visual effects shots, half of the effects shot in the entire pilot. One such effects shot, the wing falling and exploding, had been attempted manually with explosives in the wing. However, the explosives failed to detonate, and the explosion was composited in. (Season 4 Arrives!)

Polar bears are created using CGI, although originally the visual effect was attempted by a stuffed bear shot out of a cannon, according to Welcome to Oahu. See also: Kevin Blank for details on the polar bear chaps.

While 10% of the Black Rock was actually built as a set piece, the rest of the foam shapes of the rest of the ship were photographed by Kevin Blank, and composited into the shot.

The Pillar of Smoke in "Exodus, Part 1" was created using CGI. ^{[source needed]}

The Numbers on the timer are made with CGI. Though originally shot for "Adrift" and "Orientation" with a real working model, in editing they were shown to be flimsy, and didn't look mechanical enough. Kevin Blank was then approached by Damon and Carlton to make the clock CG, and the clock ended up costing just $300 per shot. (Season 4 Arrives!)

In "One of Them", the smoke in the burning oil fields was created using CGI. ^{[source needed]}

Over 160 effects shots were used for the Season Two finale. These included the four-toed statue, the sailboat, the Hurley bird, and the Hatch implosion.

(Season 4 Arrives!)

Every time Flight 815 is seen crashing, including the impact of the tail section, CGI was used. The shot was mapped out in many ways, making it fit seamlessly to the shot of the breakup from the cabin of the plane that was featured in the Pilot episode. According to Kevin Blank, "If you blew it up, you would see a couple of CG people that were in the same position [as the ones that flew out the back of the plane]." (Season 4 Arrives!)

The Island is sometimes composited with CGI. (Lost: The Complete First Season)

[8]

The backlighting and details on satellite phones used by the freighter crew, first introduced in "Catch-22", are all computer generated. Effects supervisor Mitch Suskin explains that a prop was never created because the producers originally didn't realize the device would be used so much. He describes the prop as "block of wood, basically". [9]

The highway car chase in "The Beginning of the End" was computer generated. ^{[source needed]}

The underwater search scenes in "Confirmed Dead" were computer generated. [10]

The toy airplane in the aquarium in "Confirmed Dead" was computer generated. According to Mitch Suskin, visual effects were used because the prop would not spiral the way they wanted. He also describes that the plane was originally supposed to be modeled after a Lockheed L-1011 (the prop used for Flight 815), but a decision was later made to change it to a Boeing 777 (the make of the plane in the story). He describes the result a bit of a hydrid. [11]

The Monster throws explosions in front of Jack as it uproots several trees in the process. ("Exodus, Part 2")
