Radley Metzger (born January 21 1929 in New York City) is an American filmmaker, distributor and producer. He is also known by his pseudonym Henry Paris, a name he adopted in the 1970s when he began to direct films with explicit hardcore sexual content.

In his early career, Radley Metzger was a film editor, working on such films as The Flesh Eaters, and providing censor cuts for European films like Bitter Rice. He also edited several trailers, quite a number of them for the films of Ingmar Bergman.

As an auteur, he is considered by his fans to be among the more stylish directors of the sexploitation and porn chic eras. He often shot films in Europe and collaborated a number of times with cinematographer Hans Jura.

Metzger retired from filmmaking in 1984.

Radley Metzger, one of the pioneers of the adult cinema, was born on January 21, 1929 in New York, New York. He first made his name in erotic cinema by importing and exhibiting the Swedish sex film "I, A Woman" (1966), which was a huge hit in the States. Metzger decided to make his own films, which became renowned for their great visuals. These visually arresting soft-core films, including "Therese and Isabelle" (1968), "Carmen, Baby" (1967) and "Camille 2000" (1969), were mostly shot in Europe. Other notable Metzger films of this period include "The Lickerish Quarter" (1970) and "Little Mother" (1972), a roman a clef about Eva Perod. When hard-core became lucrative after the great success of "Deep Throat" (1972), Metzger became a major part of the "porno-chic" cycle under his 'nomme de guerre' Henry Paris. His output included "The Private Afternoons of Pamela Mann" (1975), "Naked Came the Stranger" (1975), "The Opening of Misty Beethoven" (1976), and "Barbara Broadcast" (1977). It is Radley Metzger, more than anyone, who served as the inspiration for the director Jack Horner in Paul Thoams Anderson's "Boogie Nights" (1997), as he was the only director in the genre capable of making high-quality motion pictures that could compete with main-stream fare. In fact, he turned to the mainstream, directing an international cast including Oscar-Winner Wendy Hiller, in the fourth remake of the "Cat and the Canary" (1979). Metzger made one more porno film before retiring as a filmmaker in 1984.
