Haven't seen this yet, but the Midnight Madness program at the Toronto International Film Festival has often picked some great films that are highly entertaining.
This entire film is shot from a first person perspective, with some pretty crazy action sequences running throughout the film. Sharlto Copley (from District 9, Europa Report and Elysium) is in it as well, playing a hilarious number of variations of the same character (I won't spoil the twist, but he's having a lot of fun in it).
It got picked up and is getting an early 2016 release I believe. Hope you enjoy the trailer.
