Oscar-winning actor Mark Rylance has added his support to a petition to 'save' Sherwood Forest from fracking.
Ineos Shale has been granted permission to carry out seismic tests to see if there is gas reserves in the area but has always insisted fracking won't happen in protected areas.
Mr Rylance has made a video for campaign group Friends of the Earth who claim the historic forest is in danger.
In the video he says: "This is the latest threat to our increasingly industrialised countryside. I feel we have to make a special effort to protect a place like Sherwood Forest."
"We need Robin Hood back," he adds.
