Fantastic 4 (2005)

Dr. Reed Richards, a genius but timid and bankrupt physicist, is convinced evolution was triggered millions of years ago on earth by clouds of cosmic energy in space, and has calculated that one of these clouds is soon going to pass near Earth. Together with his friend, the gruff yet gentle astronaut Ben Grimm, Reed convinces his equally brilliant but conceited MIT classmate Dr. Victor Von Doom, now CEO of Von Doom Industries, to allow him access to his space station to test the effects of exposure to the cloud on biological samples. Von Doom agrees, in exchange for control over the experiment and a majority of the profits from whatever benefits it brings. He brings aboard his chief genetics researcher (and Reed's ex-girlfriend from MIT) Susan Storm and her reckless brother Johnny Storm, a young astronaut who was Ben's subordinate at NASA but is his superior on the mission.

The quintet travels to space to observe the cosmic energy clouds, but Reed has miscalculated and the clouds materialize well ahead of schedule. Reed, Susan, and Johnny leave the shielded station to rescue Ben who has gone on a space-walk to place the samples, and Victor closes the shield behind them. Ben receives full exposure out in space, while the others receive a more limited dose within the station. They return home but soon begin to develop strange powers. Reed is able to stretch like rubber; Susan can become invisible and create force fields, especially when angered; Johnny can engulf himself in fire at temperatures in excess of 4000 K (erroneously described as supernova-themed in the film), and is able to fly; and Ben is transformed into a large, rock-based creature with superhuman strength and durability. Victor meanwhile faces a backlash from his stockholders due to the publicity from the failed mission and has a scar on his face from an exploding control console he was near during the cloud's pass.

Ben returns home to see his fiancée Debbie, but she cannot handle his new appearance and flees in fear. He goes to brood on Brooklyn Bridge and accidentally causes a traffic pile-up while stopping a man from committing suicide. The four use their various powers to contain the damage and prevent anyone from being hurt. While the public cheer them for their efforts, Ben sees his fiancée leave her engagement ring on the ground and run. Reed hands a heartbroken Ben the ring and vows to find a way to turn him back to normal. The media dubs them "The Fantastic Four" for their efforts. Victor watches the news story and is told that his company is lost now, the group's fame overriding the company's fate with the media. The four move into Reed's lab in the Baxter Building to study their abilities and find a way to return Ben to normal. Victor offers his support in their efforts but blames Reed for the mission's failure, the lights flickering as he grows enraged.

Reed tells the group he will construct a machine to re-create the storm and reverse its effect on their bodies, but warns it could possibly accelerate them instead. However, Johnny refuses to give up his powers and uses them to help him win extreme sports thus exposing Reed, Susan, and Ben's abilities to the public which leads to a small fight between him and Ben after making fun of them. Johnny claims that these new powers are a “higher calling”. Meanwhile, Victor continues to mutate, his arm turning into an organic metal and allowing him to produce bolts of electricity, and he begins plotting to use his new powers to take his revenge. Victor drives a wedge between Ben and Reed, as the group's research has allowed him to rekindle his relationship with Susan. Reed and Ben argue, with Ben walking out in a rage. Susan soon scolds Johnny on how he is using his powers just to gain popularity. This motivates Reed to attempt the machine on himself, but he cannot generate the power needed to push the storm to critical mass. Victor hears Reed tell Susan this through security cameras and has Ben brought to the lab. Ben is placed in the machine and Doom uses his abilities to produce the electricity needed to power it, turning Ben back to normal and accelerating Doom's condition, causing much of his body to turn to metal. Victor knocks the human Ben unconscious and kidnaps Reed.

Victor – now calling himself "Doom" – dons a metal mask to hide his physical deformities and tortures Reed using a super-cooling unit. Doom fires a heat-seeking missile at the Baxter Building to kill Johnny, and Johnny flies through the city to evade it, lighting a garbage barge on fire to trick it. Susan rushes to confront Doom as Ben begins to regret his decision to turn normal. Susan frees Reed and battles Doom but is outmatched - Ben arrives to save her, transformed into The Thing again by reusing the machine. The battle spills into the streets, and the four assemble to battle Doom. Johnny and Susan combine their powers to wrap Doom in an inferno of intense heat, and Ben and Reed douse him with cold water, inducing thermal shock and freezing Doom in place.

As an epilogue, Ben informs Reed that he has accepted his condition with the help of Alicia Masters, a blind artist for whom he has developed feelings, and the team decide to embrace their roles as superheroes and unite officially as the Fantastic Four. Reed proposes to Susan, who accepts and they share a kiss. Meanwhile, Doom's statuesque remains are being transported back to his homeland of Latveria when the dockmaster's electronic manifest briefly experiences electronic interference.
