Sidonie Bond, 84
Sidonie Bond appears to have taken a sabbatical from the media upon her last acting gig, which is the 2001 short film Sleep, as per her IMDb page. It’s a wise option, given that any celebrity in their 80s would want peace and calmness.
Bond garnered a lot of attention for her appearances in the TV shows The Avengers (1961) and Castle Haven (1969), with both of her performances exceeding everyone’s expectations. Today, the Liverpool-born celebrity is regarded as one of the greatest actresses of all time in the United Kingdom.
