Mother Love is a 1989 BBC British television drama. It was adapted by Andrew Davies from Domini Taylor's (Roger Longrigg's) 1983 novel concerning a mother's obsessive love for her son, vengeful hatred of his father, her ex-husband, and the effect on her daughter-in-law and grandchildren. It starred Diana Rigg, David McCallum, James Wilby, and Fiona Gillies, and was directed by Simon Langton.Christopher "Kit" Vesey (James Wilby) and Angela Vesey (Fiona Gillies), a British yuppie couple, enjoy a seemingly idyllic life. Yet there is one troubling factor in their lives - Kit's mother Helena (Diana Rigg), an eccentric and often difficult woman consumed by anger with Kit's father (David McCallum), a famed conductor with whom she believes Kit has no contact.

Her oddness is confirmed in a series of incidents involving her ex-husband and his second wife Ruth (Isla Blair), an artist. Flashbacks throughout the series reveal bits of Helena's troubled past. Little by little, the young couple's life begins to fall apart as Helena begins to act out her feelings of intense jealousy and desire for revenge, implicating a dear old friend and leading to murder.
