In the 2008 film Pontypool, what carries the zombie-like infection?

In the 2008 film Pontypool, the zombie-like infection is carried through the English language.

The film adapts Tony Burgess’s novel Pontypool Changes Everything and takes place largely inside a small Ontario radio station. Radio host Grant Mazzy, producer Sydney Briar, and technician Laurel-Ann Drummond receive reports of violence outside while trying to understand what is happening.

The infection is linked to particular English words and to the way infected people process language. Speaking, hearing, and repeating affected words can help spread the condition, turning ordinary radio communication into a potential danger. This unusual premise makes the film closer to a linguistic horror story than a conventional outbreak movie.

Pontypool was directed by Bruce McDonald, with Stephen McHattie playing Mazzy. The film’s confined setting and reliance on radio reports are often compared with audio drama, even though it remains a feature film.
