Walter Jones, played by Essex Smith, is a character in the film Halloween III: Season of the Witch.
Walter is a gas station attendant who took Harry Grimbridge to the hospital after Harry was attacked by mysterious men in black. Once he turns him over to Dr. Daniel Challis he left, not wanting anything else to do with it.
Late Halloween night, several days later, Challis shows up again at the gas station telling Walter he needs the phone. Challis calls the television station operator telling them to pull the Silver Shamrock commercial. Two of the channels did, but the third did not.
