[citation needed] In 1960, Field's breakthrough came when she was chosen by Tony Richardson to play the role of model Tina Lapford in The Entertainer (1960), starring Laurence Olivier, distributed by Bryanston Films.

With those three big film starring roles in 1960, she became one of the very few actors ever to have their name above the titles in all the major cinemas around Leicester Square simultaneously.

Although offered a role in A Kind of Loving (1962), Field turned it down to play the female lead in a Hollywood financed film, The War Lover (1962), with Steve McQueen.

[citation needed] Her later television roles included Anna Lee: Headcase (1993), Murder She Wrote, Lady Chatterly, Rumble, Bramwell, Barbara, Madson, Dalziel and Pascoe, The Bill, Where the Heart Is, Waking the Dead, Monarch of the Glen, Last of the Summer Wine, Doctors.

[13] On 14 November 1993, Field appeared on BBC Radio 4's Desert Island Discs, talking to Sue Lawley about her upbringing in different children's homes in Northern England and her success as an actress in the 1960s.

[15][16] In the September 2009 issue of Cinema Retro, there was a long interview with Field, where she candidly talked about her childhood and the making of Peeping Tom, The Entertainer, Beat Girl and The War Lover.
