Cvitanovich's greatest work was for
Thames Television during the 1970s, under the enlightened reign of Director of Programmes
Jeremy Isaacs. With his then partner,
Midge Mackenzie, his first film for Thames was
Bunny (1972), a moving account of the treatment given to the couple's own brain-damaged son in a Philadelphia clinic. The film won an International
Emmy. Cvitanovich loved sport - especially the Dallas Cowboys - and his very first documentary was a study of a baseball player in decline. For Thames he made films about motorcycle champion
Barry Sheene, the footballing
Charlton Brothers and
Saturday’s Heroes (1976) about life behind the scenes at
Tottenham Hotspur F.C. Other subjects included a day in the life of an East End park, and
The Kilnsey Show about a Yorkshire wall-building competition. Yorkshire was also the setting for
Bonny, Beauty, Daisy, Violet, Grace and Geoffrey Morton (1974), which won a
BAFTA and several other awards. In 1981 Cvitanovich won a
Jacob's Award for ''Murphy's Stroke'', his TV film based on the
Gay Future betting coup. ==Private life==
