Actor and press reformer Hugh Grant is to star in a new advert promoting The Guardian and The Observer weekend supplements.

The advert is described by The Guardian as “tongue-in-cheek” and will “appear in a commercial shot like a movie trailer for a spoof Jerry Bruckheimer film, the US producer behind hits such as Beverly Hills Cop, Top Gun, Con Air and Pirates of the Caribbean”.

The ad campaign will include cinema, press, posters and escalator panels on the London Underground and online advertising.
