hi, I think I saw it few years ago. I think maybe even it was short film or full film..... the drone (robot) I think came from another world/dimension.... then chased the boy/ or just got into his house.... hided in his house.... then they interacted.... I think it was either killing drone, or robot within drone (or maybe even robot suit within the drone)..... the drone was round white and able to fly - and Feds or someone were after it I think... thanks
