The sitcom stars Anthony Head and Eve Myles as Ed and Lauren who, despite their 25-plus year age gap. fall madly in love.
Blackman plays Rose, Ed’s vital and eccentric mother, who is quite ready to cause chaos between her son and his girlfriend given half a chance.
At the age of eighty, Rose has the tireless nature of a person a quarter her age and even though she seems harmless to Lauren, Ed warns her she will create turmoil.
Speaking last year, Blackman said:“I think they are lovely people, and a terrific team and I look forward to having fun with them.
“Anthony Head and Eve Myles have a wonderful relationship; I am going to see if I can rattle their cage a bit!”
