He was shot at by John Landon with a tranquilizer gun and was shipped to Gen-Sys Laboratories for the revised ALZ-112 therapy - the ALZ-113 trials. Jeanpierre was one of the caged apes during the Gen-Sys Laboratories escape led by Caesar, Maurice and Rocket.
- Jeanpierre's name was shown on his info box when the apes at the San Bruno Primate Shelter were fired up as Dodge introduced Caesar.
- His appearance is known because of his shot in the second trailer for the film.
- It is possible that his name could be inspired by French author Pierre Boulle, who wrote the original novel.
- It is currently unknown if Jeanpierre appeared in Dawn of the Planet of the Apes.
