Photo Flash: Extempore Theatre's 2013 London Improvathon at Hoxton Hall

Produced by Extempore Theatre (the new name for award-winning experimental theatre company The Sticking Place), creators of Showstopper! The Improvised Musical and The Terror Seasons, Britain's only annual festival of horror theatre and Grand Guignol, The 6th Annual London Improvathon takes place over 50 hours from Friday 11 January at 7.00pm to Sunday 13 January at 9.00pm at Hoxton Hall. Check out photos from the event below!

The finest improvisers from all over the world flew to London to take part. This year participants come from America, Canada, Australia, Norway, The Netherlands, Austria and France, joined by the cream of UK talent.

Set in 1926, this year's theme celebrates the glory days of Carter and Egyptology - it's The Mummy meets Indiana Jones via Dorothy Parker and Agatha Christie! What secrets lie buried in the desert sands? Will there be greater discoveries than Tutenkhamun's tomb? What is the riddle of the Sphinx? And what happens when performers stay awake for over 50 hours? As our cast gather in the old hotel overlooking the market square, prepare for an epic oddesey of romance, mystery and adventure...

The Improvathon is imported from Edmonton (Alberta, Canada) where for 20 years, the Die Nasty troupe have held an annual 'Soapathon'. Discovered by the late great theatre maverick Ken Campbell in 2005, Ken brought the event to the UK where it later became produced annually by Adam Meggido and The Sticking Place.

Some of the improvisers will go the distance for a full 50 hours of non-stop performance including musicians, technicians and the director. After 30 hours without sleep, the performers are peeled back to their 'lizard brain' resulting an a wild, uncensored and euphoric playing style that you will never see anywhere else in the world! Although the action plays like four seasons of your favourite DVD box set all in one sitting, each episode is self-contained. So audiences can drop in for any 105 min episode which stands alone. Although many people get caught up in it and want to stay for more!
