A lightsaber is a fictional weapon in the Star Wars universe, a "laser sword." It consists of a polished metal hilt which projects a blade of light about 1.33 meters (1.45 yards) long. The lightsaber is the signature weapon of the Jedi order and their Sith counterparts, both of whom can use them for close combat, or to deflect blaster bolts. Its distinct appearance was created using rotoscoping for the original Star Wars films, and digitally for the prequel trilogy. The lightsaber first appeared in the original Star Wars film (1977) and every Star Wars movie to date (except The Star Wars Holiday Special) has featured at least one lightsaber duel. In 2008, a survey of approximately 2,000 film fans found it to be the most popular weapon in film history, generally seen as "fan-freakin-tastic".

The lightsaber's blade cuts through most substances without resistance. It leaves cauterized wounds in flesh, but can be deflected by another lightsaber's blade, or by energy shields. Some exotic saber-proof materials have been introduced in the Expanded Universe. An active lightsaber gives off a distinctive hum, which rises in pitch and volume as the blade is moved rapidly through the air. Bringing the blade into contact with an object or another lightsaber's blade produces a loud crackle.

Graham William Walker, known by his stage name Graham Norton, (born 4 April 1963) is an Irish actor, comedian, television presenter and columnist. He is the host of comedy chat programme The Graham Norton Show on BBC One in the UK and BBC America in the US. Hot Press has described him as "the 21st century's answer to Terry Wogan", with both men sharing an Irish background and the common link of being a BBC Radio 2 presenter and the BBC television commentator of the Eurovision Song Contest. Norton has won the BAFTA TV Award for Best Entertainment Performance on five occassions.

Norton was born in Clondalkin, a suburb of Dublin, but grew up in Bandon, County Cork, Ireland to a Protestant family. He was educated at Bandon Grammar School, in County Cork and then University College Cork but did not complete his studies.

In 1992 his stand-up comedy drag act in the Edinburgh Festival Fringe as a tea-towel clad Mother Teresa of Calcutta made the press when Scottish Television's religious affairs department mistakenly thought he represented the real Mother Teresa.
