Early life
Robin Shelby was born Robin Navlyt in Hebron, Illinois. Her family relocated to Sunnyvale, California when she was eleven years old,3 and she quickly developed a passion for acting. She trained in musical theater and dance, a background that later proved essential for conveying character expressiveness while working inside a performance suit that blocked all vision and restricted nearly all movement.
Career
Shelby's professional work centers on the specialty of character performance and suit acting, a field that demands physicality, stamina, and the ability to project emotion entirely through body movement. Her first major Hollywood assignment was at Industrial Light and Magic, where she played a troll creature pulled apart by a two-headed Hydra during the production of Ron Howard's Willow (1988).3 That collaboration established her relationship with ILM and led directly to the Ghostbusters II opportunity.4
Beyond her Ghostbusters work, her film credits include Beverly Hills Cop III (1994), where she performed as costumed theme park mascots Floyd and Axel Fox;3 a stunt double role for Spanky in The Little Rascals; a stunt double role for Luisa in The Fantasticks; and a voice performance in the short film Dolan (2016).3 She appeared in the television comedy series Cybill (starring Cybill Shepherd) and The Home Court (starring Pamela Reed).3 On the production side, she served as creator, executive producer, and lead actress on the television comedy series Far from the Tree (2011-2012) across fifteen episodes, and is a producer on the comedy series 2 Cops and a Car.3 She also appears in the documentary Cleanin' Up The Town: Remembering Ghostbusters, which chronicles the making of the original 1984 film.3

Ghostbusters II (1989)
When ILM began pre-production on the Slimer sequences for Ghostbusters II, the team drew on their prior work with Shelby on Willow and invited her to audition.4 She has recalled not knowing the project was Ghostbusters II when she first auditioned, and feeling "very, very excited" upon learning the truth.4 Stuntman Bobby Porter had originally been cast as Slimer but moved on when the character was temporarily written out during an earlier phase of scripting.1 Shelby stepped into the role.
She was approximately twenty years old at the time, weighing around 95 pounds.1 The Slimer costume, which consisted of three interlocking segments (main body, gloved arms, and head), weighed approximately 35 pounds, more than a third of her own body weight.1 Wearing the head made her completely blind, requiring ILM crew members to physically guide and reposition her between takes.1 She has described the suit's weight as the most punishing aspect of the work, surpassing even the heat generated by the costume during extended takes.4 She underwent five to six weeks of rehearsal to coordinate with the ILM puppeteers who operated the suit's animatronic elements via the SNARK system (Serial Networked Actuator Relay Kit), a radio-controlled servo mechanism developed by ILM animatronics engineer Al Coulter that allowed remote operation of Slimer's eyebrows, eyes, nose, and mouth without cable controls.1 Her total time on the production was approximately eight weeks.4
Because Slimer's scenes were filmed as visual effects composites, Shelby performed her character work separately from the principal cast in front of a blue screen.4 Despite sharing multiple scenes with Rick Moranis in the finished film, she never met him during production.4 She has expressed regret that she never had the chance to thank Harold Ramis for his contributions to the franchise.4 She formed a close friendship with Ernie Hudson, describing him as "one of the nicest people you'll ever meet," and recalls Bill Murray as "a total nut, crazy, but in a good way."4
Slimer's voice in Ghostbusters II was provided by director Ivan Reitman, who had also performed the character's vocalizations in the original 1984 film.5 Shelby's contribution was entirely physical.
Much of Slimer's planned screen time was cut from the finished film. Executive Producer Michael C. Gross explained that early test screenings produced minimal audience reaction to the character, leading the production to reduce Slimer to brief appearances rather than the originally intended expanded subplot in which Louis Tully attempts to capture him.6 A 30-second continuous shot considered by the ILM unit to be among the best footage of Slimer demonstrating a full emotional arc from sadness to happiness did not make the final cut.1
Ghostbusters: Answer the Call (2016)
For the 2016 reboot directed by Paul Feig, Shelby was recruited to voice Lady Slimer, a female counterpart to the original character who appears as Slimer's love interest.4 Feig reached out to her directly via Twitter, which she has described as a complete surprise,7 and said the decision took about two seconds. She completed all her voice work in a single day,4 collaborating with Supervising Sound Editor Becky Sullivan on the recording session.7
On June 21, 2016, Shelby publicly confirmed she had a role in the film ahead of its release. Her specific contribution as the voice of Lady Slimer was confirmed on July 9, 2016, during the live broadcast of the film's premiere.
Lady Slimer's design draws on two distinct creative inspirations: the character is a tribute to Mandy Pepperidge (played by Mary Louise Weller) from the 1978 comedy Animal House, given that Slimer himself is loosely based on John Belushi's Bluto, who marries Mandy at that film's end. Lady Slimer is also visually based on She-Devil, the wife of the Looney Tunes Tasmanian Devil.
In IDW Publishing's Ghostbusters comics, Shelby's likeness and name appear in multiple non-canonical acknowledgments. A citizen running from the Gozerian Terror Bear on page one of Ghostbusters Issue #3 is based on her, appearing in the same panel alongside Frank Welker.8 A license plate reading "SHLB" appears in panel five of Ghostbusters Crossing Over Issue #5 as a nod to her contributions to the franchise.9 Her original official website was once hosted on The Ghostbusters Fan Forum, an early GBFans.com community site, where she appeared under her birth name Robin Navlyt.
