Charles and Camilla make rare appearance
The Prince shares a joke with Larry Hagman
Prince Charles and his companion attended a society wedding in London together but arrived apart.
Then in the evening the prince went to the same film premiere as Camilla's children but again kept his distance.
The Prince greeted her with a kiss on both cheeks and chatted about his tentative foray into acting at his 50th birthday gala on Wednesday.
Ms Thompson stars as the wife of a prospective US President (John Travolta) in the film and she encouraged the Prince to go to the premiere, which raised £50,000 for the Prince's Trust and the Alone in London homeless charity.
The event, at the Empire in London's Leicester Square, was also attended by Camilla Parker Bowles's two children, Tom and Laura. But they arrived separately from the prince.
Earlier Charles and Camilla - who are rarely seen in public together despite press speculation about their blossoming relationship - attended the wedding of Santa Palmer-Tomkinson and writer Simon Sebag-Montefiore.
The Prince of Wales arrived 20 minutes after Camilla with Prince Harry and Zara Phillips.
Among the celebrity guests attending the wedding were Tiggy Legge-Bourke, Sir David Frost, Koo Stark and TV presenter Tanya Bryer.
The prince has known Santa, 28, since she was a child. She is the daughter of his skiing companions Charles and Patty Palmer-Tomkinson.
Her bridal gown was designed by Catherine Walker, who was one of Diana, Princess of Wales's favourite dress designers.
The Sebag-Montefiores are among the oldest Jewish families in Britain and made their fortune in business with the Rothschilds during the 19th Century.
The groom's great-great-great-grandfather was Sir Moses Montefiore, the first Jewish baronet and a philanthropist who was knighted by Queen Victoria.
