Question: Who was an artist, Valie Export or Neil Marshall?
Context: Valie Export (often written as 'VALIE EXPORT') (born May 17, 1940 in Linz as Waltraud Lehner, later Waltraud Höllinger) is an Austrian artist.  Her artistic work includes video installations, body performances, expanded cinema, computer animations, photography, sculptures and publications covering contemporary arts. Renate Bertlmann (28 February 1943 in Vienna) is an Austrian feminist avant-garde artist, living and working in Vienna.  She is a contemporary of Birgit Jürgenssen and VALIE EXPORT, and her work focuses on the relationship between masculine and feminine forms. The Descent is a 2005 British horror film written and directed by Neil Marshall.  The film follows six women who, having entered an unmapped cave system, become trapped and are hunted by troglofaunal flesh-eating humanoids. Betty Tompkins (born 1945) is an American artist.  Tompkins is a painter whose works revolve, almost exclusively, around photorealistic, close-up imagery of both heterosexual and homosexual intimate acts.  She creates large-scale, monochromatic canvases and works on paper of singular or multiple figures engaged in sexual acts, executed with successive layers of spray painting over pre-drawings formed by text.  Alongside artists such as Carolee Schneemann, Yoko Ono, Valie Export, Joan Semmel, Lynda Benglis and Judy Chicago, Tompkins has been re-assessed as a pioneer of Feminist art.  Tompkins is listed in The Brooklyn Museum's Elizabeth A. Sackler Center for Feminist Art's Feminist Art Base.  Her first painting, completed in 1969, is held in the permanent collection of the Centre Georges Pompidou in Paris, France. Dog Soldiers is a 2002 British action horror film written and directed by Neil Marshall, and starring Kevin McKidd, Sean Pertwee and Liam Cunningham.  A British production, set in the highlands of Scotland, it was filmed almost entirely in Luxembourg.  In the U.S., it premiered as a Sci Fi Pictures telefilm on the Sci Fi Channel. Tyler Bates (born June 5, 1965) is an American musician, music producer, and composer for films, television, and video games.  Much of his work is in the action and horror film genres, with films like "Dawn of the Dead, 300, Sucker Punch," and "John Wick."  He has collaborated with directors like Zack Snyder, Rob Zombie, Neil Marshall, William Friedkin, Scott Derrickson, and James Gunn.  With Gunn, he has scored every one of the director's films; including "Guardians of the Galaxy", which became one of the highest grossing domestic movies of 2014, and its 2017 sequel.  In addition, he is also the lead guitarist of the American rock band Marilyn Manson, and produced its albums "The Pale Emperor" and "Heaven Upside Down". The Practice of Love (German: "Die Praxis der Liebe" ) is a 1985 Austrian drama film written by and directed by Valie Export.  It was entered into the 35th Berlin International Film Festival. Neil Marshall (born 25 May 1970) is an English film director, editor and screenwriter.  Marshall began his career in editing and in 2002 directed his first feature film "Dog Soldiers", a horror-comedy film which became a cult film.  He followed up with the critically acclaimed horror film "The Descent" in 2005.  Marshall also directed "Doomsday" in 2008, and wrote and directed "Centurion" in 2010.  He has also directed two prominent episodes of US television series "Game of Thrones": "Blackwater" and "The Watchers on the Wall", with particular acclaim for his direction on both occasions, as well as a nomination for a Primetime Emmy Award for Outstanding Directing for a Drama Series for "The Watchers on the Wall". Centurion is a 2010 British historical action-war film directed by Neil Marshall, loosely based on the disappearance of the Roman Empire's Ninth Legion in Caledonia in the early second century AD.  The film stars Michael Fassbender, Dominic West, and Olga Kurylenko.  It received mixed to positive reviews and performed poorly at the box office, only earning half of its $12m budget. Doomsday is a 2008 science fiction action horror film written and directed by Neil Marshall.  The film takes place in the future in Scotland, which has been quarantined because of a deadly virus.  When the virus is found in London, political leaders send a team led by Major Eden Sinclair (Rhona Mitra) to Scotland to find a possible cure.  Sinclair's team runs into two types of survivors: marauders and medieval knights.  "Doomsday" was conceived by Marshall based on the idea of futuristic soldiers facing medieval knights.  In producing the film, he drew inspiration from various movies, including "Mad Max", "Escape from New York" and "28 Days Later".
