London After Midnight, also known as The Hypnotist, was a 1927 American silent mystery film with horror overtones directed by Tod Browning and starring Lon Chaney, Marceline Day, Conrad Nagel, Henry B. Walthall and Polly Moran.
 The film was distributed by Metro-Goldwyn-Mayer, and was based on the short story "The Hypnotist" by Tod Browning, who also directed the film.
Norman Tokar (November 25, 1919 in Newark, New Jersey – April 6, 1979 in Hollywood) was a prolific director (and occasionally writer and producer) of serial television and feature films, who directed many of the early episodes of "Leave it to Beaver", and found his greatest success directing over a dozen films for Walt Disney Productions, spanning the 1950s to the 1970s.
West of Zanzibar is a 1928 American silent film directed by Tod Browning about the vengefulness of a cuckolded magician (Lon Chaney) paralyzed in a brawl with his rival (Lionel Barrymore).
 The supporting cast includes Mary Nolan and Warner Baxter.
 The picture is based on a 1926 Broadway play called "Kongo" starring Walter Huston.
 Huston starred in the 1932 talkie film adaptation of the same story using the "Kongo" title.
 "West of Zanzibar" is also famous with horror film fans for having lost or excised sequences that Browning filmed; in particular, Phroso (Chaney) as a duckman in a sideshow act and scenes showing Phroso and his troupe when they first arrive in Africa.
Freaks is a 1932 American MGM Pre-Code horror film produced and directed by Tod Browning, originally 90 minutes running time, the film was later re-edited into 64 minutes, after several scenes were cut.
 The film was based on elements from the short-story Spurs by Tod Robbins.
 The eponymous characters were played by people who worked as carnival sideshow performers and had real deformities.
 The film stars Wallace Ford, Leila Hyams, Olga Baclanova and Roscoe Ates.
 Among the deformed cast were dwarf siblings Harry and Daisy Earles, the torsoless Johnny Eck, the conjoined twin sisters Daisy and Violet Hilton, and Schlitzie.
 The original version of the film was considered too shocking to be released and no longer exists.
 "Freaks" has been described as standing alone in a subgenre of one.
Outside the Law is a 1920 American crime film directed by Tod Browning and starring Lon Chaney.
 Browning would remake the film in 1930 with a pre-"Little Caesar" Edward G. Robinson in Chaney's role as a gang leader.
"Spurs" is a short story by Tod Robbins.
 The story was published in February 1923 in "Munsey's Magazine" and included in Robbins' 1926 anthology "Who Wants a Green Bottle?
 and Other Uneasy Tales".
 In 1932 the story became the basis for the Tod Browning produced film "Freaks".
Mark of the Vampire (also known as Vampires of Prague) is a 1935 horror film, starring Lionel Barrymore, Elizabeth Allan, Bela Lugosi, Lionel Atwill, and Jean Hersholt, and directed by Tod Browning.
 It is a talkie remake of Browning's silent "London After Midnight" (1927), with the characters' names and some circumstances changed.
Jim Bludso is a 1917 American drama film directed by Tod Browning.
 It was Browning's first feature film as a director.
 Contemporary sources are variable on the matter of whether the direction was a joint effort between Browning and the film's star, Wilfred Lucas.
 In their book "Dark Carnival: The Secret World of Tod Browning, Hollywood's Master of the Macabre," David J. Skal and Elias Savada suggest that Lucas' name was added to the credit for contractual reasons, and that Browning directed "Jim Bludso" alone.
 As "Jim Bludso" is presumed lost, it is uncertain what the original title card might have read in terms of directorial credit.
 The film was produced by the Fine Arts unit within the Triangle Film Corporation, the same studio that made the popular Douglas Fairbanks comedies for Triangle, for whom Browning had previously worked as a scenarist.
Tod Browning (born Charles Albert Browning, Jr.; July 12, 1880 – October 6, 1962) was an American motion picture actor, director and screenwriter.

Errol Taggart (July 15, 1895 – August 30, 1940) was a Canadian film director and film editor who worked in Hollywood during the 1920s and 1930s.
 He was the editor of four movies directed by Tod Browning and starring Lon Chaney: "The Unknown" (uncredited) with Joan Crawford, "The Road to Mandalay", "The Blackbird", and the lost film "London After Midnight" (uncredited).
 He also edited Browning's film "Drifting" featuring Wallace Beery and Anna May Wong in supporting roles, and was Browning's first assistant director on "Freaks" (uncredited) featuring Olga Baclanova and a cast of actual carnival sideshow freaks.
 Taggart also directed seven films, including "Sinner Take All", "Song of the City", and "The Women Men Marry".
