Coronation Street's Michael Le Vell is determined to save fields near his home from development.
The 54-year-old soap actor appeared in a video in which he expressed his "shock" that developers are planning to build 2,400 houses near his property in Timperley, Greater Manchester.
Michael said: "My name is Michael Le Vell and this is the first time I've heard of this. It goes on for miles. I'm shocked.
"All the Green Belt is going and no-one seems to know about it. Why are there no posters up? Why are residents not being informed and all this?"
A source told the Daily Star newspaper: "He's really angry about the plans. The way he sees it is huge swathes of the countryside are being turned over to housing and eventually there will be nothing left.
"He is determined to help fight to get the plan halted."
Campaigners have claimed that 70 per cent of the properties will not be affordable for locals.
Michael - who has been on the hit ITV soap opera since 1983 - is best known for his role as mechanic Kevin Webster.
The development plans near his home are not only thing which has shocked Michael recently.
Last year, he admitted being "surprised" to hear how quickly sepsis can affect the human body after researching a "Coronation Street" storyline about the condition.
He said: "What the show does is well is it picks the right moments to shock, and when not to shock.
"We're only playing pretend but to lots of families out there it's real life.
"I was talking to a guy last week, Matthew. He and his wife went on honeymoon three years ago and both got a sore throat. His wife responded to the antibiotics, he ended up with five months in hospital, five months in a coma, five cardiac arrests, lost part of his legs.
"This is just from a sore throat on honeymoon.
"I was surprised how quick it [sepsis] can affect the body."
In the "Corrie" plot, Kevin's son Jack Webster (Kyran Bowes) had to have his leg amputated after the youngster was struck down with sepsis, a serious complication of an infection, also known as blood disease.
