 The actors playing the Green Street Hooligans had to work out with  the productions trainer for four or five hours every day. The  trainer, Pat Johnson, had most of the actors throwing up, he was  working them so hard. A typical day would involve basic strength and  fitness training for about two hours, followed by choreographing of  the fight sequences. Rehearsals would take place in the afternoon,  and then in the evening they would all go out drinking (which is  probably why most of them were throwing up the next day).  Elijah Wood (qv) was absented from most of this rigorous schedule  to emphasize his outsider status.
