Marlena Evans is a fictional character on the NBC daytime drama, Days of Our Lives, a long-running serial about working life in the fictional town of Salem. She has been played by actress Deidre Hall since 1976, but the character was absent from the show from 1987 to March 1991 and again from January 2009 to September 2011. Marlena was created by scriptwriter Pat Falken Smith and executive producer Betty Corday, and has become one of Days of our Lives' most well-known characters. Hall made her debut on the soap on June 21, 1976, currently making her the second longest running actress on the serial, surpassed only by Suzanne Rogers (Maggie Horton). Throughout the course of her existence on the program, she has experienced what some consider to be the most outrageous circumstances of any character in soap opera history. These would include being possessed by the devil two times (in 1994 and 2021); a plummet from a 30-story-window (which she survived); being used as a surrogate for genetically engineered babies, Rex and Cassie, during a four-year coma, where she was presumed dead after being involved in a plane crash; being mind-controlled to believe she was a serial killer; being targeted by several serial killers; and becoming pregnant late in life and suffering a miscarriage, which caused her to have hysterical amnesia. She has also been kidnapped numerous times over the past 45 years. She is a doctor, wife, mother, twin, grandmother and great-grandmother. Marlena is a staple in the US press during her time on Days of Our Lives, a representative of the symbiosis between American's soaps and tabloid soap magazines. Widely read tabloids, such as Soap Opera Digest and Soap Opera Weekly, would routinely publish forthcoming developments in Marlena's storylines. Marlena was well received by critics, and is notable for her popular pairing with John Black. The character is well-known even outside of the show's viewer-base. In 2010, Sheri Anderson (a former head writer for Days) began writing books about off-screen characters from the soap. John and Marlena were included in one called A Secret in Salem.
