The Queen is a 2006 British drama film directed by Stephen Frears, written by Peter Morgan, and starring Helen Mirren in the title role, Elizabeth II of the United Kingdom. Released almost a decade after the event, the film depicts a fictional account of the immediate events following the death of Diana, Princess of Wales on 31 August 1997.

The main plot focuses on the differing views in how to deal with the death of Diana. The Royal Family, while on their summer residence at Balmoral Castle, sees her death as a private affair, not to be treated as an official Royal death, in contrast with newly appointed Prime Minister Tony Blair and Diana's ex-husband Prince Charles, who attempt to reflect the public wish for an official expression of grief. Matters are further complicated by the media, royal protocol regarding Diana's official status, and wider issues about republicanism. The views of Diana's two sons throughout the film are only portrayed through other characters.

The film's release coincided with a revival of favourable public sentiment with respect to the monarchy and a downturn in fortunes for Blair, whose resignation came less than a year later.

The film exceeded box-office expectations; with a budget of $15 million the film has earned $56.4 million in the United States and has a worldwide gross of $120 million.

Before the film was released, critics praised both Stephen Frears and Peter Morgan, who later garnered Golden Globe and Academy Award-nominations for Best Director and Best Screenplay. Michael Sheen's performance as Tony Blair earned him particular acclaim. Helen Mirren's portrayal garnered her acclaim from critics around the world. Her portrayal made her a favourite for the Academy Award for Best Actress well before the film was released in theatres. After its showing at the Venice Film Festival, Mirren received a five-minute-long standing ovation. Roger Ebert came out of recovery from surgery to give the film a review. He called it "spellbinding" and gave it four out of four stars. The Queen was the most critically acclaimed film of 2006 with Mirren being the most critically acclaimed actress of the year. The Queen has 97% positive reviews on the film-critics aggregate site Rotten Tomatoes.

The film won an Academy Awards at the 79th Academy Awards for Actress In A Leading Role (Helen Mirren) and it was nominated for Best Picture, Best Director (Stephen Frears), Best Original Screenplay and so on.
