It's a terrible shame that it is so impossible to find this TV series Ora zero e dintorni
However, in a fotoromanzo magazine from 1981 I found this advertisement for the series:
It looks like all of the actors from the series are credited in the ad, and that is a great help! There is particularly one name which is interesting: Stefano Stefanelli
. According to the IMDb he plays a child in an episode of the TV series Sam & Sally
(1978-80) and also appears in the film Masoch
(1980). I know there is a DVD release of Sam & Sally
but I don't know about the availability of Masoch
. I really need to check and see if he is our boy!!
