He might be old enough to draw a pension, but it seems Harrison Ford is in no mood to retire just yet. With the long-awaited return of his ophiophobic ("why did it have to be snakes!") archaeologist, there's no better time to kick off Six Degrees than with Indiana Jones himself. Outside of the film set, Ford has a reputation for being a bit grumpy, so it's difficult to imagine him bonding with the chipper, tennis-loving popstar Sir Cliff Richard. If you're scratching your head to find the connections, then read on as DS presents a route from Harrison to Cliff through Six Degrees Of Separation.

Harrison Ford to... Tom Selleck - Strange as it sounds, Harrison Ford wasn't the first choice to play Indiana Jones back when George Lucas and Steven Spielberg were looking to cast their all-action hero for Raiders Of The Lost Ark. Tom Selleck was the original pick for the iconic role but was forced to drop out of the running after his TV show Magnum PI was picked up for a series. Film buffs can get a sample the mustachioed smoothie as Indy by checking out his screen test on the Indiana Jones DVD extras.

Tom Selleck to... Courteney Cox - Though Selleck must have been kicking himself for losing out on the chance to play Indiana Jones, solace came for the actor on TV as the Hawaiian shirt-wearing PI Thomas Magnum. That trademark 'tache would later become a familiar sight on sitcom Friends. His character Richard proved something of a rival to Chandler as the pair fought for the affections of Courteney Cox's Monica.

Courteney Cox to... Bruce Springsteen - Long before Courteney cemented herself as a sitcom star she took part in a bit of staged concert spontaneity for a famous rock star. The music video for Bruce Springsteen's anthemic 'Dancing In The Dark' saw the New Jersey rock legend pull a young Courteney from the audience to dance with him. That music vid bop inspired Bruce to reprise the "pull-a-girl-from-the-crowd" trick for his live shows. Maybe we'll see some of those fans pop up in smash-hit sitcoms years from now?

Bruce Springsteen to... Tina Turner - In 1985 the Boss joined a supergroup to record the charity single 'We Are The World'. Penned by Michael Jackson and Lionel Richie, the track was the highest-selling of the year and provided much needed famine-relief for Ethiopia. The all-star group featured a laundry list of famous pop acts and, weirdly, Ghostbusters's Dan Akroyd. Tina Turner, who recently announced a comeback tour, notably provided vocals with Bruce on the song.

Tina Turner to... Cliff Richard - Our last leap heads from a veteran US performer to a British musical institution. When Sir Cliff Richard was putting together his 70th studio album Wanted he was looking for hits "he'd always wanted to record". Songs from Elvis and the Beatles may have been expected but his admiration and subsequent cover version of Turner's 'What's Love Got To Do With It' probably raised a few eyebrows among his devoted fan base who were probably expecting songs a bit tamer.
