Threesome (2014)

Original title: เธอ เขา เรา ผี

Arpa Pawilai is appealingly cast as Som, an ordinary young woman who works as a movie make-up artist. Her longtime live-in boyfriend Rang is also in the business. But the handsome musclebound prop guy – always wearing tight, biceps-baring vest T-shirts – captures many adoring eyes, like that slutty actress, but also his straight-acting gay boss and just about anyone else with a pulse. Som has about had it with Rang being distracted by all the flirting.
