He is portrayed by Christopher Lloyd in all three films and in the television series and was loosely inspired by Leopold Stokowski and Albert Einstein.

[1][3] Devo co-founder Mark Mothersbaugh also recalled being approached by Robert Zemeckis and Steven Spielberg for the role, but turned it down because he was not interested in acting.

[4] Producer Neil Canton suggested Lloyd to Bob Gale and Zemeckis, as he had previously worked with him on The Adventures of Buckaroo Banzai Across the 8th Dimension.

"[6] Lloyd was significantly younger than his character, being 46 years old at the time of filming Back to the Future, so the makeup artists made him look older.

[7] Lloyd recalled discussing his inspirations with Zemeckis, after he was influenced by an album cover depicting Stokowski in front of the cosmos with white hair.

Although the script was rejected more than 40 times, Steven Spielberg showed interest in producing the film at Amblin Entertainment.

[9] Storyboard artist Andrew Probert said that Doc Brown's car was designed to be a DeLorean, but Gale had to reject various offers from automotive companies that wanted to be included in the film.

The scenes involving Doc Brown's 1955 mansion home, which in the film is located at the fictional address of 1640 Riverside Drive in Hill Valley, California, were shot at the Gamble House in Pasadena.

Fox for the part of Marty McFly in the sixth week of filming, Lloyd was initially worried by the casting change, as he was concerned about having to reshoot the scenes.

[14] In Back to the Future Part III, Doc Brown develops a relationship with Clara Clayton in 1885, a character portrayed by Mary Steenburgen.

Zemeckis explained that the third film illustrates the character's growth from an eccentric to a man capable of falling in love: "he gets in touch with that boyish, romantic, innocent part of himself".

Emmett Lathrop Brown[18] is a white-haired scientist who is called "Doc" by his teenage friend Marty McFly.

[21] Doc was born into a wealthy family and in 1955 lives in a mansion, but spends thirty years burning through his wealth to realise his vision of time travel.

Marty typically seeks out his friend each time he finds himself in a perilous situation, knowing that Doc will provide a solution.

[28] Gale said that Doc's friendship with Marty is based on mutual respect, as both characters find a connection with each other being rebellious by nature.

While trying to hang a clock in his bathroom by standing on the toilet, he slipped, banged his head and while he was knocked out had a vision of the flux capacitor, the component that makes time travel possible.

[31] In 1985, he uses stolen plutonium to create a "nuclear reaction to generate 1.21 gigawatts of electricity" to power the DeLorean and enable it to time travel.

[33] When Doc Brown meets Clara Clayton in 1885, he finds romance with a character who is similarly eccentric and interested in science.

[25] GamesRadar+ listed Doc Brown as one of the greatest movie characters of the 1980s alongside Marty, particularly praising their onscreen chemistry.
