Helen Margaret Montagu[1] (21 April 1928 – 1 January 2004) was an Australian stage producer, actress, and impresaria in London.
She attended Sydney University, where she met her future husband, a psychologist named Russell Willett; the couple married in 1953.
In 1975 she was named as the managing director of H. M. Tennent, basically a repertory company, presenting The Seagull and The Bed Before Yesterday on alternate weeks with largely overlapping casts at the Lyric Theatre.
[2] On one occasion, the night when the French ambassador went to see Madeleine Renaud performing in Beckett's Oh, Les Beaux Jours, she received an anonymous phone call after curtain up warning of a possible bomb [clarification needed] on the premises, but she did nothing, and told no one.
[3][5] She produced musicals, including a musical version of Prisoner: Cell Block H, as well as a production of The Who's Tommy, in addition to reworking classics such as Chekhov's The Seagull, and introducing new innovative or original productions (The Elocution of Benjamin Franklin and The Bed Before Yesterday).
