Siccin 4

Siccîn 4 is a 2017 Turkish horror film written and directed by Alper Mestçi, and the fourth entry in the Siccîn series. Produced by Muhteşem Tözüm, it stars Merve Ateş, Sebahat Adalar, Yasemen Büyükağaoğlu and Adnan Koç.

The once-wealthy Yılmaz family falls on hard times and is forced to move in with grandmother Saadet. But Saadet is not alone in her old house, where her husband's grave sits in the garden: unseen inhabitants from another realm have already claimed the place. The family's arrival is far from welcome, for these beings want no one in the house besides Saadet.

Filmed in Kısıklı, Ömerli, Garipçe, Beykoz and Kemerburgaz, the movie opened on 1 September 2017 and became the first film released in 4DX format in Türkiye.
