I, Frankenstein is a 2014 American science fantasy action film written and directed by Stuart Beattie, based on the digital-only graphic novel by Kevin Grevioux. An international co-production between the United States and Australia, the film was produced by Tom Rosenberg, Gary Lucchesi, Richard Wright, Andrew Mason and Sidney Kimmel. It stars Aaron Eckhart, Bill Nighy, Yvonne Strahovski, Miranda Otto and Jai Courtney. The film tells the story of Adam, Frankenstein's creature, who embarks on a dangerous journey to stop evil demons and their ruthless leader from taking over the world.

The film was released on January 24, 2014, in the United States and on March 20, 2014 in Australia. The film received extremely negative reviews, although Nighy's performance was praised, and was a box-office bomb, grossing $76 million worldwide against a production budget of $65 million.

In 1795, Doctor Victor Frankenstein creates a monster by putting together parts of corpses and reanimating them. Horrified by his creation, Frankenstein tries to destroy it, but the monster survives and murders his wife Elizabeth. Frankenstein chases it to the Arctic, but he succumbs to the cold weather. When the monster returns home to bury Frankenstein, it is attacked by demons, but is then rescued by two gargoyles, Ophir and Keziah. They bring it to a cathedral, where the monster meets the gargoyle queen Leonore and her second-in-command Gideon. Leonore explains that they were created by the Archangel Michael to battle demons on Earth and protect humanity. She names the creature "Adam" and invites him to join them, but he declines and chooses to depart. He is given baton-like weapons to protect himself, as more demons will come after him. The weapons allow him to "descend" demons (destroying their bodies and trapping their souls in Hell) as they have the symbol of the Gargoyle Order carved on them.

For the next two hundred years, Adam lives apart from society, killing any demon that pursues him and hiding from them. Deciding to rejoin society in the modern-day, Adam looks for and confronts a group of demons. During the fight, a police officer is killed. This causes Adam to be summoned by the gargoyles once more and they decide to imprison him as punishment. A demon Helek, who survived Adam's attack, reports to his leader, the demon prince Naberius, that Adam is alive. Naberius has disguised himself as billionaire businessman Charles Wessex and employs scientists Terra Wade and Carl Avery to conduct experiments to try to reanimate corpses. He sends a group of demons led by his most formidable warrior, Zuriel, to attack the gargoyles' cathedral and capture Adam so he can unlock the secret to resurrecting the dead.

In the attack, many demons are slain and 16 gargoyles, including Ophir and Keziah, are "ascended" (returned to and trapped in Heaven), but Zuriel sneaks in and captures Leonore and takes her to an abandoned theater. Adam interrogates a demon who tells him that they lured the gargoyles out in order to capture Leonore so they can force the gargoyles to trade Adam for her. Gideon is instructed to trade Adam to them; however, Adam escapes after the attack. Without Adam, Gideon instead offers to trade Frankenstein's journal for Leonore, which was found on Doctor Victor Frankenstein's body on the night they found him. At the theater, Gideon gives Zuriel the journal and Leonore is spared. Adam follows Zuriel to the Wessex Institute, where he discovers thousands of corpses underground and learns that Naberius plans to recreate Frankenstein's experiment by reanimating the corpses and using them as hosts for the descended demons so he can rebuild his armies and destroy humanity. Adam retrieves the journal from Terra and escapes the demons. He later tracks down Terra and asks for her help. The two are then attacked by Zuriel, where Adam fights him and manages to descend him.

Adam warns the remaining gargoyles of Naberius' plan, agreeing to give them the journal if they get him and Terra to safety. Leonore agrees and when Adam leaves, she secretly sends Gideon to kill him after he retrieves the journal. After a violent fight, Adam ascends Gideon and then decides to burn Frankenstein's journal and destroy its secrets before the gargoyles come after him. Luring them out of the cathedral, Adam leads them to the Wessex Institute, where they descend Naberius's right-hand man Dekar and then battle more demons. In the ensuing battle, Adam goes into the institute to rescue Terra, who had been kidnapped by Naberius and forced to begin the process of reanimating the corpses. Naberius overpowers Adam and tries to have one of the demon spirits possess him, but it doesn't work because Adam has developed a soul of his own. Adam carves the Gargoyle Order symbol on Naberius, descending him to Hell. The institute collapses and falls into an abyss, where all the demons and all the possessed corpses are destroyed and Naberius' plan is thwarted. Leonore rescues Adam and Terra from falling into the abyss as well and they return to the cathedral.

Leonore forgives Adam for Gideon's death and Adam bids farewell to Terra. In the ending scene, Adam narrates that he will continue defending the world from demons as he declares himself "Frankenstein".

Much doubt has been cast over a sequel due to the film's lackluster box office performance, though Kevin Grevioux, creator of the graphic novel and the Underworld film series, had earlier expressed interest in making more I, Frankenstein films along with an Underworld crossover film. He stated in a pre-release interview that, in an early draft of his screenplay, Kate Beckinsale would have made a post-credits cameo appearance as Selene and that there would have been Underworld Easter eggs, but none of this was used.^[30]
