Animal rights activists have posted banners encouraging motorists to watch a vegan documentary across a motorway bridge near Bristol.
The banners, which are situated on the M32 motorway, say: "Land of Hope and Glory, watch on YouTube."
Land of Hope and Glory is a documentary by Ed Winters and Luna Woods. It has been described as the 'British Earthlings'.
Speaking to PBN, the pair said: "We're so pleased and humbled to see that word about 'Land of Hope and Glory' is being spread all over the country in such creative ways.
"It's so important that the film reaches a non-vegan audience and the banner drop is such a brilliant way of ensuring as many people as possible hear about the film."
The film, which uses never seen before undercover footage, exposes the brutal reality of factory farming in the UK, that is present even on so-called 'higher welfare' assured farms.
It is believed some of the footage comes from welfare charity RSPCA-Assured farms.
The film's release on August 1 generated some controversy for its unflinching portrayal of animal agriculture, with the RSPCA branding it as 'upsetting'.
A spokesperson added: "This film is clearly very upsetting and we are concerned about the footage, particularly given claims some of it was taken on a RSPCA-Assured farm.
"We take all animal welfare complaints extremely seriously but unfortunately, the filmmakers have not contacted us with details of their concerns, so we haven’t yet been able to investigate."
The charity refused to respond to PBN's questions about the legitimacy of its 'assurance' scheme.
