The extended opening of The Incomer, written and directed by Louis Paxton, is very funny and engaging. Far away and remote on a lonely, lovely Scottish isle, siblings Isla (Gayle Rankin) and Sandy (Grant O’Rourke) live simple, quiet lives. They mourn their parents, most recently their father, and they watch out for trespassers on their land—Incomers, they call them. Cue the meek government official, Daniel (Domhnall Gleeson), charged with getting the duo off the island and back to the mainland. Isla and Sandy proceed to playfully torture Daniel as he fails in his overtures to convince them to leave.
