John Constantine appeared in the 2005 film Constantine portrayed by Keanu Reeves. The film used some elements from Garth Ennis' "Dangerous Habits" story arc (issues No. 41–46) and others—such as the inclusion of Papa Midnite—from the "Original Sins" trade paperback. The film changed several aspects of the source material, however, including a number of cosmetic changes to the lead character, e.g., his name is spoken as "constan-teen", and Reeves played the role with his natural accent and hair colour, as well as the film basing him in Los Angeles (although the director pointed out that the comic book was not exclusively set in London either). Other differences to the comic were made, for example giving him a psychic ability to see "half breeds" as they truly are—a curse that caused him to attempt suicide which in turn damned him to Hell. He was also given the ability to render invisible beings in his proximity visible by using the incantation "Into the light I command thee" and two magical glyphs (called "The Perfect Red King" from Eugenius Philalethes's "The Speculum Veritatis") on his arms to combine, which he uses to uncloak the archangel Gabriel directly after he attacked his friend Chas. Unlike the comic version, Constantine's exorcism tools are primarily based on Christian relics rather than generic supernatural items; the novelisation expanded on this by explaining that, as Constantine comes from a Christian culture, he has a greater natural understanding of the power of Christian relics that makes it easier for him to use them. Constantine's exorcisms are motivated by a desire to redeem himself for his past suicide, yet they are constantly doomed to fail as everything he has done has fundamentally been for his own benefit rather than for the selfless betterment of others. The resolution of the lung cancer plotline in the film was also amended, with Lucifer saving the redeemed Constantine to give him a second chance at failing after Constantine willingly sacrificed a chance to save his own life to ask Satan to send the innocent Isabel Dodson to Heaven (Isabel having committed suicide to prevent herself being used as a host for a demonic incursion). This selfless deed allowing Constantine to regain his place in Heaven. Constantine was also restored to life and his lung cancer was removed.
