Keep It Up Downstairs (also known as Can You Keep It Up Downstairs? and My Favorite Butler), is a 1976 British period sex comedy film, directed by Robert Young and starring Diana Dors, Jack Wild and William Rushton.^[1] It was written by Hazel Adair.

The film follows the adventures of the sex-crazed inhabitants of the bankrupt Cockshute Castle in 1904, and the attempts of Lord and Lady Cockshute to find a rich wife for their uninterested inventor son Peregrine.

It was shot at Elstree Studios and on location at Knebworth House in Hertfordshire. A version exists with hardcore inserts; these were shot with body doubles for the main stars.^[2]

The score was by Michael Nyman, his first for a commercially released film.

Monthly Film Bulletin said "A joyless 'romp' that is soporifically heavy-handed with its phallic imagery and double meanings (endless references to "big ones" and "getting it off"), Keep It Up Downstairs bungles the tempting possibility of a ribald melange of Upstairs Downstairs and The Go-Between [1971] school of sensitive historical drama. The cast, required to bare breasts and buttocks at regular intervals, is able to make no headway against the inane script and consistently mistimed direction."^[3]
