Parkpoom Wongpoom and Banjong Pisanthanakun, the duo who directed the hit ghost flick, Shutter, will remain together and work on Alone as their project.
The story is about a couple who travel from Korea to set up home in Thailand.
It could be set up as a Korean-Thai joint production or be fully financed by Thai studio GMM Tai Hub, Variety says.
The pair had previously announced they would split up and concentrate on their own dramas, with Parkpoom working on Life With a Mission, about political kidnappings, while Banjong was readying Aids Diary, Variety says.
Producer Mingmongkol Sonakul told Variety they would shoot Alone in March and then return to their individual efforts.
