Celador Films and Pathe are re-teaming for a sequel to 2005's acclaimed spelunking horror hit "The Descent" says The Hollywood Reporter.
The Neil Marshall-directed feature, costing under $10 million, took in nearly six times that at the box-office internationally.
The script sees the survivor forced back into the system of caves she battled her way out of in the first film, in a bid to locate the rest of her group.
The stars of the original film, Shauna MacDonald and Natalie Mendoza, will reprise their roles, alongside Gavan O'Herlihy, Joshua Dallas, Anna Skellern, Douglas Hodge and Krysten Cummings.
Based on a script by James Watkins ("My Little Eye"), the $10 million sequel will shoot more than eight weeks on location in Scotland and at London's Ealing Studios.
Editor Jon Harris will make his directorial debut on the flick.
