Emmerdale Uncovered: Live, to be screened immediately after the main ITV1 event in October, will feature backstage action in front of a studio audience of superfans.
An insider told the Daily Star: "Emmerdale Uncovered: Live will get right to the heart of all the action.
"We will be getting all the reaction from the cast as soon as they come off air and speaking to the crew about how they managed to pull it all off."
However, many more details are still to be revealed about the programme, including the casting of a presenter.
Digital Spy exclusively reported back in May that Emmerdale would screen a live special to celebrate its 40th anniversary.
The director of the special was last month confirmed to be Tony Prescott, who shot Coronation Street's 50th live episode in 2010.
Stars Lucy Pargeter (Chas Dingle), Dominic Power (Cameron Murray), Charley Webb (Debbie Dingle) are known to be playing big roles in the live drama, with their on-screen love triangles set to come to a head.
