Sir Michael John Gambon, CBE (born 19 October 1940) is an Irish actor who has worked in theatre, television and film. A highly respected theatre actor, Gambon is recognised for his roles as Philip Marlow in the BBC television serial The Singing Detective, as Jules Maigret in the 1990s ITV serial Maigret, and as Professor Albus Dumbledore in the last six Harry Potter films (following the death of actor Richard Harris).

Gambon was born in Cabra, Dublin, during World War II. His father, Edward Gambon, was an engineer, and his mother, Mary (née Hoare), was a seamstress. His father decided to seek work in the rebuilding of London, and so the family moved to Mornington Crescent in North London, when Gambon was five. His father had him made a British citizen, a decision that would later allow Gambon to receive an actual, rather than honorary, knighthood and CBE.

Brought up as a strict Roman Catholic, he attended St Aloysius Boys' School in Somers Town and served at the altar. He then moved to St Aloysius' College in Hornsey Lane, Highgate, London, whose former pupils include Peter Sellers and Joe Cole. He later attended a school in Kent, before leaving with no qualifications at fifteen. He then gained an apprenticeship with Vickers Armstrong as a toolmaker. By the time he was 21, he was a fully qualified engineer. He kept the job for a further year, acquiring a fascination and passion for collecting antique guns, clocks, watches, and classic cars.

Jonathan Stephen Ross, OBE (born 17 November 1960) is an English television and radio presenter, best known for presenting the BBC One chat show Friday Night with Jonathan Ross from 2001 until he left the BBC in 2010. Ross began hosting a new chat show on ITV1 starting 3 September 2011. Ross also hosted his own radio show on BBC Radio 2, and acted as a film critic and presenter of the Film programme. Other regular roles have included being a regular panellist on the comedy sports quiz They Think It's All Over from 1999 to 2006, and presenting the annual British Comedy Awards from 1991 to 2007, and 2009 onwards.

Ross began his television career as a programme researcher, before débuting as a television presenter for The Last Resort with Jonathan Ross on Channel 4 in 1987. Over the next decade he had several radio and television roles, many through his own production company, Channel X. In 1995 he sold his stake in Channel X, and embarked on a career with the BBC. In 1999, Ross took over presenting the Film programme from Barry Norman, and also began presenting his own radio show, while two years later he began hosting Friday Night with Jonathan Ross. For the chat show, Ross won three British Academy of Film and Television Arts (BAFTA) awards for Best Entertainment Performance, in 2004, 2006 and 2007. By 2006 Ross was believed to be the BBC's highest paid star. In 2005, Ross was made an Officer of the Order of the British Empire (OBE) for services to broadcasting. Ross has been involved in controversies throughout his broadcasting career. As a result, in 2008 he wrote a semi-autobiographical work titled Why Do I Say These Things?, detailing some of his life experiences.

Jeremy Charles Robert Clarkson (born 11 April 1960) is an English broadcaster, journalist and writer who specialises in motoring. He is best known for his role on the BBC TV show Top Gear along with co-presenters Richard Hammond and James May. He also writes weekly columns for The Sunday Times and The Sun.

From a career as a local journalist in Northern England, Clarkson rose to public prominence as a presenter of the original format of Top Gear in 1988. Since the mid-1990s, Clarkson has become a recognised public personality, regularly appearing on British television presenting his own shows and appearing as a guest on other shows. As well as motoring, Clarkson has produced programmes and books on subjects such as history and engineering. From 1998 to 2000 he also hosted his own chat show, Clarkson.

His opinionated but humorous tongue-in-cheek writing and presenting style has often generated much public reaction to his viewpoints. His actions both privately and as a Top Gear presenter have also sometimes resulted in criticism from the media, politicians, pressure groups and the public.
