Some context: Dr. Victor Von Doom (commonly known as Doctor Doom, or simply Doom) is a fictional character appearing in American comic books published by Marvel Comics. The son of a Romani witch, Von Doom has been depicted as a supervillain, the archenemy of the Fantastic Four, and the leader of the fictional nation called Latveria. While his chief opponents have been the Fantastic Four, he has also come into conflict with Spider-Man, Iron Man, Black Panther, and multiple others. Von Doom has also been depicted as a superhero, being the third character to take up the mantle of Iron Man and joining the Avengers.
In 1976, Marvel and DC Comics collaborated on Superman vs. the Amazing Spider-Man, and seeking to replicate that success the two companies again teamed the characters in Superman and Spider-Man in 1981. Marvel editor in chief Jim Shooter co-wrote the story with Marv Wolfman, and recalled choosing Victor von Doom based on his iconic status: "I figured I needed the heaviest-duty bad guy we had to offer -- Doctor Doom. Their greatest hero against our greatest villain."  The same year, John Byrne began his six-year run writing and illustrating Fantastic Four, sparking a "second golden age" for the title but also attempting to "turn the clock back [...] get back and see fresh what it was that made the book great at its inception." Doctor Doom made his first appearance under Byrne's tenure with issue #236. Whereas Kirby had intimated that Doom's disfigurement was more a figment of Victor's vain personality, Byrne decided that Doom's face was truly ravaged: only Doom's own robot slaves are allowed to see the monarch without his helmet. Byrne emphasized other aspects of Doom's personality; despite his ruthless nature, Victor von Doom is a man of honor. Returning to Latveria after being temporarily deposed, Doctor Doom abandons a scheme to wrest mystical secrets from Doctor Strange in order to oversee his land's reconstruction. Despite a tempestuous temper, Doom occasionally shows warmth and empathy to others; he tries to free his mother from Mephisto and treats Kristoff Vernard like his own son. Byrne gave further detail regarding Doom's scarring: Byrne introduced the idea that the accident at Empire State University only left Victor with a small scar that was exaggerated into a more disfiguring accident by Doom's own arrogance--by donning his newly forged face mask before it had fully cooled, he caused massive irreparable damage.  After Byrne's departure Doom continued to be a major villain in Fantastic Four, and as the 1980s continued Doom appeared in other comics such as Punisher, The Spectacular Spider-Man, and Excalibur. Under Fantastic Four writer Steven Englehart, Doom became exiled from Latveria by his heir Kristoff, who was brainwashed into thinking he was Victor von Doom. Doom would spend most of his time in exile planning his return, but Englehart left the title before he could resolve the storyline. This storyline ultimately ended with the controversial Fantastic Four #350, where writer Walt Simonson had the Victor von Doom who had been seen in the book during the Englehart run being revealed to be a robotic imposter and the real Von Doom, in a newly redesigned armor, returning to claim his country from his usurper. According to Simonson's retcon, the last appearance of the real Victor von Doom was in the "Battle of the Baxter Building" story arc, but Simonson's interpretation of the character was unaware of certain major changes at the time to the Fantastic Four. Simonson drew up a list of stories which featured the real Doom and those which did not but later writers ignored Simonson's choices, retconning these story elements as an attempt by Doom to blame his own past failures on unruly robots.

Some context: Joan Agnes Theresa Sadie Brodel was born on January 26, 1925, in Highland Park, Michigan, the youngest child of John and Agnes Brodel. John was a bank clerk and Agnes was a pianist. Joan's two older sisters, Betty and Mary Brodel, shared their mother's musical interest and started to learn how to play instruments, such as the saxophone and the banjo, at an early age. They began performing in front of audiences in acts that included singing and dancing.
By 1946, Leslie was growing increasingly dissatisfied with the roles offered to her by the studio. She sought more serious and mature roles and wanted to break out of her ingenue image which was partly due to her young age. Her decision was also based on moral and religious grounds. With the help of her lawyer Oscar Cummings, she took Warner Brothers to court in order to get released from her contract.  In 1947, the Catholic Theatre Guild gave Leslie an award because of her "consistent refusal to use her talents and art in film productions of objectionable character."  As a result of this, Jack Warner used his influence to blacklist her from other major Hollywood studios. In 1947, she signed a two-picture contract with the poverty row studio Eagle-Lion Films. The first one was Repeat Performance (1947), a film noir in which she played a Broadway actress. The other was Northwest Stampede (1948) in which she performed with James Craig.  After her contract with Eagle-Lion Films expired, she was cast in The Skipper Surprised His Wife (1950), appearing with Robert Walker. The film was distributed by MGM, the studio in which she began her film career in 1936.  In the early 1950s, Leslie chose to focus on raising her daughters, which resulted in a more irregular film career. In 1952, she signed a short-term deal with Republic Pictures, the low-budget studio which primarily produced western pictures. One of the films she made for Republic was Flight Nurse (1953). Leslie's character, Polly Davis, was based on the successful flight nurse Lillian Kinkella Keil's career in the Air Force. It was described by the newspaper Kingsport Times-News as a thrilling film that "honors the courageous women who performed miracles of mercy above the clouds in evacuation of wounded GIs from Korean battlefields." Her last film was The Revolt of Mamie Stover (1956). However, she continued making sporadic appearances in television shows while her children were at school. She retired from acting in 1991, after appearing in the TV film Fire in the Dark.
