On Thursday, Daniel Radcliffe, Emma Watson and Rupert Grint wore red poppy pins to the world premiere of Harry Potter and the Deathly Hallows: Part 1 in London, but it wasn't just to look coordinated.
The pins are actually part of a tradition for Rememberance Day, a British holiday like our Veterans Day in which people honor those who have served. The premiere of the highly anticipated film was scheduled on the same day as the holiday, which is why the three stars and other cast members were paying their respects.
But Canadians like Justin Bieber and Cory Monteith would have been able to pinpoint the reason behind the HP7 crew's premiere accessories in a heartbeat. The red poppy became Rememberance Day tradition from the Canadian war poem 'In Flanders Fields,' which makes reference to the flower as a symbol of blood shed during World War I.
