Question: What American Western filmmaker's film did Norman Lumsden appear in?
Context: Norman Lumsden (16 September 1906 – 28 November 2001) was a British opera singer and actor.  He first came to prominence during the 1940s and 1950s in several operas by composer Benjamin Britten, often performing at Covent Garden and the Aldeburgh and Glyndebourne festivals.  He later began a television acting career during the 1970s appearing mostly in small roles in TV dramas.  He branched out into films during the 1980s, notably appearing in Clint Eastwood's 1990 film "White Hunter, Black Heart."  He is particularly remembered for his portrayal of J.R. Hartley in the 1983 Yellow Pages advert "Fly Fishing by J. R. Hartley", in 2015 voted fifth most popular British TV advertisement. Deadwood is an American western television series created, produced, and largely written by David Milch, that aired on the premium cable network HBO from March 21, 2004, to August 27, 2006, spanning 36 episodes and three seasons.  The series, set in the 1870s in Deadwood, South Dakota, before and after the area's annexation by the Dakota Territory, charts Deadwood's growth from camp to town, incorporating themes ranging from the formation of communities to western capitalism.  The show features a large ensemble cast, and many historical figures appear as characters, such as Seth Bullock, George Crook, Wyatt Earp, E. B. Farnum, George Hearst, Wild Bill Hickok, Calamity Jane, Jack McCall, Sol Star, Al Swearengen, and Charlie Utter.  The plot lines involving these characters include historical truths as well as substantial fictional elements.  Milch used actual diaries and newspapers from 1870s Deadwood residents as reference points for characters, events, and the look and feel of the show.  Some of the characters are fully fictional, although they may have been based on actual persons. So This Is London is a 1930 American Pre-Code comedy film directed by John G. Blystone and starring Will Rogers, Irene Rich, Frank Albertson and Lumsden Hare. Scotland Yard is a 1930 American crime film directed by William K. Howard, written by Garrett Fort, and starring Edmund Lowe, Joan Bennett, Donald Crisp, Georges Renavent, Lumsden Hare and David Torrence.

Rhythm on the Range is a 1936 American Western musical film directed by Norman Taurog and starring Bing Crosby, Frances Farmer, and Bob Burns.  Based on a story by Mervin J. Houser, the film is about a cowboy who meets a beautiful young woman while returning from a rodeo in the east, and invites her to stay at his California ranch to experience his simple, honest way of life.  "Rhythm on the Range" was Crosby's only western film (apart from the 1966 remake of "Stagecoach") and is notable for his introduction of two important western songs, "Empty Saddles" by Billy Hill and "I'm an Old Cowhand from the Rio Grande" by Johnny Mercer, the latter becoming a national hit song for Crosby.  The film played an important role in popularizing the singing cowboy and western music on a national level. Winchester '73 is a 1950 American Western film directed by Anthony Mann starring James Stewart, Shelley Winters, Dan Duryea and Stephen McNally.  Written by Borden Chase and Robert L. Richards, the film is about the journey of a prized rifle from one ill-fated owner to another and a cowboy's search for a murderous fugitive.  The movie features early film performances by Rock Hudson as an American Indian, Tony Curtis, and James Best.  The film received a Writers Guild of America Award nomination for Best Written American Western.  This is the first Western film collaboration between Anthony Mann and James Stewart.  It was filmed in black and white. The Law of the 45's is a 1935 American western film directed by John P. McCarthy.  The film is also known as The Mysterious Mr. Sheffield in the United Kingdom.  The screenplay was based on the 1933 novel of the same name by William Colt MacDonald.  It was the first film to be made of MacDonald's characters "The Three Mesquiteers" that later became a film series at Republic Pictures.  Though only two of the characters, Tucson and Stoney appeared in this film, Williams would appear as the missing member "Lullaby" Joslyn in "Powdersmoke Range" shot in the same year for RKO. 3 Godfathers is a 1948 American Western film directed by John Ford and filmed (although not set) primarily in Death Valley, California.  The screenplay, written by Frank S. Nugent and Laurence Stallings, is based on the novelette of the same name written by Peter B. Kyne.  Ford had already adapted the film once before in 1919 as "Marked Men."  The original silent adaptation by Ford is thought to be lost today.  The story is something of a retelling of the story of The Three Wise Men in an American Western context.  Ford decided to remake the story in Technicolor and dedicate the film to the memory of long-time friend Harry Carey, who starred in the 1919 film "Marked Men".  Carey's son, Harry Carey, Jr., plays one of the title roles in this 1948 film. Clinton Eastwood Jr. (born May 31, 1930) is an American actor, filmmaker, musician, and political figure.

These roles, among others, have made Eastwood an enduring cultural icon of masculinity.
