"It was exciting. It was like, I am acting with my sister... you live together, eat together, now you work together... So it's kind of irritating. But once you get into it, and get into the actor mode, it's great. It was exciting," Saqib said.
The title of the film will be announced later this month, he shared.
Released in 2013, 'Oculus' is the story of a brother and sister battling paranormal activity. Saqib and Huma will be reprising the characters played by Karen Gillan and Brenton Thwaites.
