British actress Emma Thompson, along with her sister Sophie, broke court injunction to protest against fracking on a Lancashire site.

The Oscar winner and her sister, also an actress, staged a parody of the show "Great British Bake Off" on a land near Fylde which was leased for drilling. Aptly titled "The Frack Free Bake Off," the two actresses filmed an "episode" with the activist group Greenpeace to stand against any fracking activities by Cuadrilla, an oil and gas exploration company, as reported by The Guardian.

The injunction, or authoritative order, has been placed in 2014, banning protesters from the area. However, this did not stop the team from shooting their satirical take on the bake off to speak against fracking.

The sisters baked energy-themed cakes, showing wind turbines and solar power, and released a series of videos on their work. The full episode, which can be viewed below, has also been released.

The "Nanny McPhee" actress said she has been made aware of the fracking issue with her involvement with Greenpeace.

"It came to a head for me when David Cameron went to the Paris Climate Conference and signed on to the protocol," Emma said in the same report. "Then on the sly at Christmas, when nobody was looking, [he] gave the nod to 200 fracking sites in Britain."

"It proved to me our government is saying one thing and doing the opposite," she added.

However, not everyone is pleased with their action.

The farmer who owns the land they trespassed on got "very upset," as reported by The Telegraph. Irate for not being able to continue his work on the field, he drove a muck spreader around the makeshift studio and the protesters, spraying raw sewage to crew members. The liquid poop, however, narrowly missed the Thompsons and their cakes.

Police came to the area but made no arrests.

Fracking, or hydraulic fracturing, is a process used to extract natural gas by drilling deep into rock formations. While supporters say fracking can add to the world's energy supply, those who oppose it say that it can contaminate water. A study also revealed several US states are at high risk for earthquakes due to fracking, putting millions of American lives in danger.

This is not the first time that Emma Thompson joined causes for the environment. The Guardian also reported that she joined a week-long protest last year at Shell's headquarters in London to protest Arctic drilling.

Other celebrities who are also well-known advocates of environmental causes are Leonardo diCaprio, Robert Redford, Julia Louis-Dreyfus and Daryl Hannah.
