Warner Bros. bans advance screenings in Canada

Bosses at movie giants Warner Bros. have banned all advance screenings of its films in Canada, claiming piracy is rife in the country.

The studio's forthcoming releases 'Ocean's 13', 'Harry Potter and the Order of the Phoenix' will not be shown north of the US border ahead of their release after Warner executives decided copyright laws in Canada fail to sufficiently protect films from being illegally copied.
