Philip Adrian Booth

Philip Adrian Booth (born 19 February 1960) is a British-Canadian-American filmmaker and musician who has made several documentaries on ghosts and exorcisms, often in collaboration with his twin brother, Christopher Saint Booth. Together, they directed several horror movies in the 2000s, with some notable actors, such as Matthew McGrory.

Originally from Halifax, West Riding of Yorkshire, he moved to Canada in the 1970s. There he played guitar in the band Sweeney Todd, in which his older brother John was the drummer and his twin brother (Christopher) as the singer. He performed several live shows with the band, but they broke up before releasing any music. He and Chris also performed as a duo under the name Who's Who?. After moving to Los Angeles in the 1980s, the brothers started working odd jobs such as production assistants and licensed some of their songs to pornographic film producers. The experience inspired them to later make their own movies.

One of their licensed songs was used in the 1986 pornographic film Angels of Passion. The song became a popular internet phenomenon after a portion of it was uploaded to WatZatSong in 2021 without identification, which led to internet searches for the song. In April 2024, the song was identified as "Ulterior Motives".
