Novocaine is a 2001 black comedy thriller film written and directed by David Atkins and starring Steve Martin, Helena Bonham Carter, Laura Dern, Lynne Thigpen and Elias Koteas. The film was shot in the Chicago, Illinois area, during a limited 32-day schedule. The film received extra publicity during production and as its release approached because of an off-the-screen romance between Martin and Carter. The film received mixed reviews, and low box-office receipts.

Generally, the film is a dark and quirky "tragicomedy" concerning an "everyman" protagonist a fairly pleasant but rather innocuous, ordinary and uneventful life. But all of this gets derailed, and Frank's life descends into an increasingly complex mess, from the minute a beautiful and seductive new patient named Susan Ivey (Helena Bonham Carter) comes to him, seeking a root canal and a little pain relief...

On Susan's initial office visit, Frank schedules her for a root canal the very next day, and offers her some Ibuprofen to address her pain in the meanwhile. Claiming that she is allergic to the offered medication, Susan requests a prescription for the addictive pain-killer Demerol. Frank provides the prescription, but only for five tablets. However, Susan changes the dosage from five tablets to fifty when she collects the medication from her pharmacist.

Procaine is a local anesthetic drug of the amino ester group. It was used primarily to reduce the pain of intramuscular injection of penicillin, and it was also used in dentistry. Owing to the ubiquity of the trade name Novocain, in some regions procaine is referred to generically as novocaine. It acts mainly by being a sodium channel blocker.

Procaine was first synthesized in 1905, shortly after amylocaine. It was created by the German chemist Alfred Einhorn who gave the chemical the trade name Novocaine, from the Latin nov- (meaning new) and -caine, a common ending for alkaloids used as anesthetics. It was introduced into medical use by surgeon Heinrich Braun. Prior to the discovery of Stovaine and Novocaine, cocaine was the most commonly used local anesthetic.

Procaine is used less frequently today since more effective (and hypoallergenic) alternatives such as lidocaine (Xylocaine) exist. It has been discontinued from US markets. Like other local anesthetics (such as mepivacaine, and prilocaine), procaine is a vasodilator, and is often coadministered with epinephrine for the purpose of vasoconstriction. Vasoconstriction helps to reduce bleeding and prevents the drug from reaching systemic circulation in large amounts. Unlike cocaine, procaine does not have the euphoric and addictive qualities that put it at risk for abuse. Cocaine is also not a vasodilator.

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.

Martin came to public notice as a writer for the Smothers Brothers Comedy Hour, and later became a frequent guest on The Tonight Show.
