Furneaux is a former participant in the Up series, an ongoing documentary series which follows the lives of fourteen British citizens in seven-year intervals, beginning when they were seven years old in 1964. Furneaux declined to participate in the series after the 21 Up episode, broadcast in 1977. After Charles declined to appear in 28 Up, during a subsequent phone conversation, director Michael Apted, by his own admission, "went berserk", which destroyed the relationship to the degree that Charles has refused to participate in all subsequent films. Allison Pearson, writing for The Telegraph, reports that Apted alleged Furneaux had filed a lawsuit aimed at "remov[ing] Charles' likeness from the archive sequences in 49 Up".
Furneaux has also participated in one of the original television series in which a viewer was encouraged to voice their opinions regarding current television programmes, Right to Reply, in 1998.
