Does anyone know if "Theo against the rest of the world" is the title of a German early 70s filmaqbout a small boy who steals a LORRY/TRUCK AND DRIVES AROUND
It is the title of a German movie from 1980. A truck gets indeed stolen, but, as I remember, the movie is more about the main character Theo chasing the truck through Europe. In fact I am not sure if the truck is recovered at the end, but a kid driving it around is definitely not part of the plot. Theo is played by Marius Müller-Westernhagen, a rather well known singer.
