L (character)/Netflix

"Justice allowed to run rampant isn't justice at all... it requires a certain attention to detail, and morality. When you relinquish yourself of that, you're making a grave mistake."

- LaKeith Stanfield interviewing in-character as L, August 2017

L is a main character in Netflix's 2017 live-action film Death Note. After criminals begin mysteriously dying en masse, L begins to investigate and narrows his suspects to Light Turner.

Appearance
L is a man in his mid-twenties, with large, bagged eyes and brown skin. Though above average in height, his hunched posture makes him appear shorter. He is usually seen in a black hoodie.

Character
L initially appears calculating and composed, coordinating cases around the world. He is shown to be profoundly intelligent and driven, but also reliant on Watari for many of his basic needs - even his sleep schedule. For all his intellect, L is immature and prone to rage when separated from Watari or otherwise feels he has lost. This rage leads him to forsake his principles (such as never carrying firearms) in an effort to catch "Kira".

Separated from Watari, he struggles in the outside world. Used to getting his way, L is unconcerned by the effect his strange posture and superior attitude have on others.

L has a voracious sweet tooth, and uses sugar to keep his mind active when sleep-deprived.

History
L was raised in an orphanage in upstate New York, part of a group trained to become the world's greatest detectives. To join the program, he was confined in a mind-warping room for months, with no way out. It is unknown how precisely this confinement affected him. The school was abandoned soon after L joined, however, and he has since been trained and managed by Watari.

By 2017, L was regarded as one of the world's greatest detectives, albeit "eccentric".

Plot
L starts the movie at the top of his game, having seeded various major databases with the names and faces of obscure criminals. When the Japanese gang rivals assigned to Seattle die in a nightclub massacre, L and Watari travel to the United States. There, they meet up with the FBI and local police and take inventory of all their information on Kira. Knowing there is no hope if Kira can kill anyone, L appears on live television mocking Kira. Since he doesn't die, the investigation assumes Kira cannot kill without a person's name or face. The FBI investigators, however, die in a mass suicide. Light is deduced to be the primary suspect, so James speaks against Kira on live television and isn't killed. L confronts Light directly to further prove his guilt.

When Watari vanishes, L's world begins to unravel. He visits the Turner household to demand the safe return of Watari. To James's frustration, he orders agents to ransack the building.

When Watari is killed, L's rage fully consumes him and he takes a gun in an attempt to hunt down Light Turner and avenge his mentor, but is knocked unconscious by a Kira worshiper before he can fire.

After being taken into custody by the police, L is able to avoid prison due to his contacts in the government, but he is deported and is to be sent back to Japan. Before his plane takes off, L remembers Mia's involvement with Light and he breaks into Mia's house. He searches through her belongings and finds a page of the Death Note with the names of the FBI agents on it. Out of anger, L grabs a pen and considers writing Light's name down.

Watari
Watari is an extremely important figure in L's life. A coordinator, liaison, manager, mentor, and father figure, L relies on him for nearly everything.

James Turner
L respects James Turner's commitment to the law, despite popular acceptance of Kira. James puts up with L's odd habits and dangerous plans, but initially objects to his son being investigated.

Light Turner
L, suspecting and confronting Light Turner, quickly proves to himself that Light is Kira. When Light separates Watari from him, however, L's full fury is directed at the teen killer.

Quotes
"You're the one that flew into the sun. I'm just here to make sure you burn."

Character changes
Compared to most adaptations, L's character and background have significant changes. Prior to the events of the film, L was raised in an orphanage in New York where he and several other children were trained by Watari to become the greatest detectives in the world. The orphanage was eventually abandoned soon after L's departure. L also rarely took time to sleep and ate nothing but sweets and required Watari's aid to maintain his health.

Towards the film's third act, L displays an aggressive behavior that causes him to shout and even break things when he is angered.

Behind the scenes
LaKeith Stanfield, the actor portraying L, watched the Death Note Anime and read the Manga to find inspiration for his character. He initially envisioned the story as closer to older versions, and adapted his portrayal to work with changes as they came up, especially L covering his face.

Regarding his character's race and online controversy, he found it exciting to have a different portrayal and invited viewers to make their own conclusions.

Trivia

 * The changes to L's characterization in the Netflix movie parallel Mello from the Manga and Anime.
 * L and Mello both find their judgement impaired by strong emotions, and use force to catch Kira.
 * L's violence leads to him being dismissed from the Kira case. Mello's rashness led him to be rejected as a successor to the manga's L, and by extension the Kira case.
 * L's name, Lebensborn, originated from a eugenics program in Nazi Germany; see Lebensborn on Wikipedia.
 * Stanfield's interview as L took the character's eccentricities to comical new heights, rubbing his knees at the mention of the Death Note and sniffing his interviewer to get to know him.
