The fourth of five movies director Rudolf Zehetgruber made about a yellow Volkswagen beetle with many gadgets. He played the driver Jimmy Bondi himself under the stage name Robert Mark. Aldo Regozzani returns from the previous episode as a race driver. Walter Giller is back as well, but in a totally different part (last time a gangster, this time a hotel employee). Part 4 is a race movie again like the first movie, but instead of Africa set in Switzerland against a beautiful scenery of snowy mountains and castles. The screenplay writing, in opposite to the photography, leaves a lot to be desired. It is the usual race routine with accidents, tricks and rivalries. The only new ability of Dudu is that he can talk now, but that leads only to a few cheap jokes. Again he can fly, which helps to win the race, but also means he can quickly leave his driver behind if he's angry with him... Mildly entertaining, but the series gets tired at this point. I voted 4-7-6-5-3 for the five movies.
