Supernatural thriller “Shomer” is materializing with “The White Queen” star Aneurin Barnard on board and Lawrence Bender (“Inglourious Basterds”), Lauren Selig and Ray Ricord producing.

The project was unveiled on the eve of the American Film Market. Exclusive Media has picked up international rights to “Shomer” and will be selling them at AFM.

“Shomer” is in pre-production and will be directed by Spanish filmmaker Guillem Morales (“Julia’s Eyes”) from a script by David Abram Nahmod. Len Blavatnik of Access Industries will exec produce with Aviv Giladi and Vince Holden of AI Film. Giladi is also financing “Shomer.”

Barnard will portray a 25-year-old man chosen to be a shomer, a person required by ancient biblical law to stay with a corpse and recite prayers until final burial. As he begins his overnight vigil with the body of a doctor, inexplicable occurrences begin to take place that show a powerful evil possessing the corpse.

“Guillem Morales is the perfect director for ‘Shomer,’ which is a great Polanski-esque version of ‘The Exorcist’ and we are delighted to have Aneurin Barnard who is such an accomplished young actor cast in the lead role,” said Bender.

Exclusive Media is also selling a pair of films in post-production at AFM — Gillian Greene’s directorial debut “Murder of a Cat,” a comedy  starring Fran Kranz, Nikki Reed, JK Simmons, Blythe Danner and Greg Kinnear with producers Sam Raimi, Molly Hassell and Ivan Orlic; and Participant Media’s “Out of the Dark,” starring Julia Stiles and Scott Speedman.
