Rocos had an early non-speaking part as a green-skinned alien in the first episode of the Hitchhiker's Guide to the Galaxy television series (1981), demonstrating the effects of a Pan-Galactic Gargle Blaster.
According to Rocos she was later lunching at the BBC with The Hitchhiker's... director Alan Bell when they were approached by Jim Moir, later Head of Light Entertainment, who asked her to audition for a new show he was developing.
The role would also be echoed in her similar appearances in the 1985 TV sketch series Assaulted Nuts, and later in reports for the consumer affairs show That's Life!.
[7] Rocos went on to remark in 2013 that the show would not be made in modern times on account of "professional campaigning women with thick ankles and shrill ovaries who have nothing better to do than to police people’s opinions".
She also made a few appearances in the Ugly Bloke slot, as an incongruously glamorous escort to physically unattractive males, on Chris Evans' Channel 4 series TFI Friday in about 1996.
[citation needed] Other TV credits include an acting role in US drama series Highlander,[11] presenting and co-producing a short Channel 5 series on the dresses of Princess Diana (whom she knew personally[8]), participating in BBC game shows such as Wipeout, Blankety Blank and Ready, Steady, Cook, and partaking in Channel 5's karaoke show Night Fever.
Although her television work became less frequent after Everett's 1995 death, during the late 1990s she presented quirky reports from exotic locations for the long-running ITV travel show Wish You Were Here...?.
She was voted off the show on 26 January 2007 as part of a surprise joint eviction along with singer Jo O'Meara, a former member of pop group S Club 7.
