Jimmy

Jimmy is a Producer, stunt pilot and driver for the Spectrum show Whitley's Guide. He never removes his helmet on-screen, and is usually presented as mute, but has provided off-screen dialogue on at least one occasion. Like host Jax McCleary, he has a British accent.

He is shown to be a competent pilot, though he is also shown to get into trouble while piloting on some occasions. He briefly served as the main host of the show for one episode during Intergalactic Aerospace Expo 2951.

The possibility of two Jimmies
As well as his on-screen appearances, numerous calls and references are made to an off-screen Jimmy, who is on one occasion referred to as a Producer of the show. While it assumed that there is only one Jimmy, this is not wholly confirmed. It is possible that there is an alternative Producer Jimmy who performs off-screen tasks and has been heard to speak, and an entirely mute on-screen Jimmy who is only the stunt pilot and onetime host.
