Producer Iain Macleod teased: “What you can expect is truly massive.
“We talked about doing something in the autumn, where money is no object, we just go nuts, and show Coronation Street is back.
“I wrote down my outline and I thought there’s no way we can do it, it’s too ambitious.
“When the crew said yep, I picked my jaw off the floor; we created something visual, dramatic, heartfelt and full of twists which I hope that will have some moments you will never see coming.
“It’s got spectacular stuff and the end result is anything more ambitious than we have ever done before.
“It exceeds everything we have done due to the technical elements.”
