From 2000 to Probate: the Complete Timeline of Michael Gambon and Philippa Hart’s Relationship
The relationship began in 2000 during the production of the historical drama Longitude. Gambon, then 59, played clockmaker John Harrison. Philippa Hart, a respected set designer 25 years his junior, worked on the production crew. What started as professional collaboration turned into a romance that Gambon chose not to hide from his theatrical circle. Within a year, he began openly introducing Hart as his girlfriend to co-stars, including Charles Dance and Maggie Smith, while filming Robert Altman’s 2001 period mystery Gosford Park.
Gambon had been married to Lady Anne Miller, a mathematician and retired educator, since 1962. Together they raised their son, Fergus Gambon, who later gained public recognition as a ceramics expert on the BBC's Antiques Roadshow. When the relationship with Hart became established, Gambon neither divorced Lady Anne nor abandoned his marriage. Instead, he forged a domestic arrangement that divided his weeks between two distinct households.
Colleagues across British theater knew of the situation. Gambon's close peers never treated it as tabloid fodder. Hart worked extensively across major television projects, building a distinguished portfolio that stood independent of Gambon’s acting fame.
