Ben Affleck's film Argo tells the story of how in 1980 the CIA - with Canadian help - sprang a group of Americans from Iran after they escaped a US embassy overrun by protestors.

A fake Canadian film project was devised, with the aim of smuggling the escapees out of the country as members of the production team.
