Mum & Dad (2008)

Perry Benson and Dido Miles are a couple who work at the airport and live off what they steal from airplanes in the British fright flick Mum & Dad (2008). They also live with their adopted children, Birdie (Ainsley Howard) and Elby (Toby Alexander), in a house of horrors where they torture and kill victims they kidnap from the airport. When Birdie takes a liking to a maid (Olga Fedori), she is faced with the choice of joining Mum and Dad or becoming their next victim. There’s no skin here, but we do get to see Olga's panty-clad bum & that’s not bad.
