Ken James skipping into TV history with new ad for mobility scooters Former Skippy star Ken James at Waratah Park / Pic: Supplied by Prosight. FORTY years since filming Skippy The Bush Kangaroo, actor Ken James has reprised the role of Mark Hammond. James returned to Sydney's Waratah Park, where the original Skippy was filmed, this month to film a tongue-in-cheek TV ad campaign for a mobility scooter. He's joined by Geoff Harvey, former Midday musical maestro, showing off the Prime Mobility Scooters as they fang it around what used to be Skippy's Ranger Headquarters. James scored the role of Mark Hammond, son of head ranger Matt Hammond (Ed Devereaux) in the series that debuted on Australian television in 1966. Skippy went on to become one of our most successful international TV exports and is still broadcast in some countries today.
