A study of one of the biggest rivalries in football to date, two of Scotland’s biggest teams, Glasgow Rangers FC and Glasgow Celtic FC. The rivalry itself is deeply rooted in Scotland’s religious divide between catholics and protestants. Originally aired in the late 90’s from this film we get a glimpse into this ‘Old Firm’ rivalry which fuelled many assaults and some deaths, on days were the two teams played against each other. A group that monitors sectarian activity in Glasgow has reported that acts of violence increase ninefold over your typical levels on match days.
