When Ray is walking through the city of Manchester at the beginning of the movie, for a few seconds Karl Marx and Friedrich Engels can be seen talking together on the street (Marx is the smaller one with white hair and beard; Engels is the taller one with the mustache). Both men were living in Britain at the time the film takes place.
Early in the first Manchester sequence a pub is seen. It's name is clearly seen as the Rovers Return, which is the name of the pub in the popular Manchester-based TV soap opera Coronation Street (1960).
