ERROR 2010 - an international festival of homeless and disabled theatres - was held on December 3 and 4 in the premises of Štúdio 12 at the Theatre Institute in Jakubovo Square in Bratislava, Slovakia. The 4th year of this international festival of plays performed by homeless and disabled people consisted of eight theatre groups from Visegrad Group countries -- Hungary, Poland, the Czech Republic and Slovakia -- and also a special guest from India. I produced this video to show the great work done by these individual groups and to highlight the importance of the work, that helps disadvantaged and socially excluded people rightfully gain acceptance and respect in the wider community.
