Wondering what “Game of Thrones” star Natalia Tena was doing yesterday? She was hard at work on a new paranormal thriller from Matador Pictures and Content Media. Yeah, that’s no reason for her not to have answered your calls… your heavy breathing is just asthma, we know.

Residue is the name of the film and it began production today under the helm of TV director Alex Garcia (“Utopia”). Created and written by John Harrison (Book of Blood), the story follows photojournalist Jennifer Preston as she uncovers a supernatural cause behind an explosion that has left her city in chaos.

Tena is best known for playing Nymphadora Tonks in the Harry Potter franchise and Osha, protector of young Rickon Stark, in HBO’s “Game of Thrones.”
