Question: What English actor appeared in films like “The Invisible Man” and “Robin Hood” while costarring with Lon Chaney JR in the 1941 edition of “The Wolf a man”?
Context: Universal Monsters is a phrase used to describe the horror, suspense and science fiction films made by Universal Studios during the decades of the 1920s through the 1950s.  They began with "The Hunchback of Notre Dame" and "The Phantom of the Opera", both silent films starring Lon Chaney.  Universal continued with talkies including monster franchises "Dracula", "Frankenstein", "The Mummy", "The Invisible Man", "The Wolf Man" and "Creature from the Black Lagoon".  The films often featured Bela Lugosi, Boris Karloff and Lon Chaney, Jr. William Claude Rains (10 November 188930 May 1967) was an English film and stage actor whose career spanned 46 years.  After his American film debut as Dr. Jack Griffin in "The Invisible Man" (1933) he appeared in classic films like "The Adventures of Robin Hood" (1938), "Mr. Smith Goes to Washington" (1939), "The Wolf Man" (1941), "Casablanca" and "Kings Row" (both 1942), "Notorious" (1946), and "Lawrence of Arabia" (1962). Of Mice and Men is a 1939 American drama film based on the 1937 play based on the novella of the same title by American author John Steinbeck, and starring Burgess Meredith, Betty Field and Lon Chaney, Jr. The supporting cast features Charles Bickford, Roman Bohnen, Bob Steele and Noah Beery, Jr. The film tells the story of two men, George and his mentally challenged partner Lennie, trying to survive during the dustbowl of the 1930s and pursuing a dream of owning their own ranch, instead of always working for others.  Starring in the lead roles were relative Hollywood newcomer Burgess Meredith as George, and veteran actor Lon Chaney, Jr. (the son of famed silent film actor Lon Chaney) as Lennie.  Chaney had appeared in more than 50 films to that point in his career, but "Of Mice and Men" was his first major role. The Wolf Man is a 1941 American horror film written by Curt Siodmak and produced and directed by George Waggner.  The film stars Lon Chaney, Jr. in the title role, and features Claude Rains, Evelyn Ankers, Ralph Bellamy, Patric Knowles, Béla Lugosi, and Maria Ouspenskaya in supporting roles.  The title character has had a great deal of influence on Hollywood's depictions of the legend of the werewolf.  The film is the second Universal Pictures werewolf film, preceded six years earlier by the less commercially successful "Werewolf of London" (1935). House of Frankenstein is a 1944 American monster crossover horror film starring Boris Karloff and Lon Chaney Jr., directed by Erle C. Kenton, written by Curt Siodmak, and produced by Universal Studios as a sequel to "Frankenstein Meets the Wolf Man" the previous year.  The cast includes a mad scientist (Karloff), the Wolf Man (Chaney), Count Dracula (John Carradine), a hunchback (J. Carrol Naish), and Frankenstein's monster (Glenn Strange).  This "monster rally" approach would continue in the following film, "House of Dracula", as well as the 1948 comedy "Abbott and Costello Meet Frankenstein". The Marriage Bargain is a 1935 American film starring Lon Chaney Jr.  It was the last film in which Lon Chaney Jr was billed under his real name Creighton Chaney. House of the Wolf Man is an American independent monster horror film produced in 2009 by My Way Pictures.  The film was inspired by the Universal Monsters movies, and was shot in the same style.  The film's star Ron Chaney is the great-grandson of Lon Chaney and the grandson of Lon Chaney, Jr., both of whom starred in numerous Universal Monsters films. Robin Hood is a fictional character who is the protagonist in Walt Disney Productions series’ 21st animated feature film Robin Hood (1973).  Robin Hood is voiced by Shakespearean and Tony Award winning actor Brian Bedford.  The film is based on the legends of Robin Hood and Reynard the fox, a 12th century Alsatian fairy tale character, but uses anthropomorphic animals rather than people.  The story follows the adventures of Robin Hood, Little John and the inhabitants of Nottingham as they fight against the excessive taxation of Prince John, and Robin Hood wins the hand of Maid Marian. House of Dracula is a 1945 American monster crossover horror film released by Universal Pictures.  It was a direct sequel to "House of Frankenstein", and continued the theme of combining Universal's three most popular monsters: Frankenstein's monster (Glenn Strange), Count Dracula (John Carradine), and the Wolf Man (Lon Chaney Jr.).  The film, which was the seventh Universal film to feature Frankenstein's monster, as well as the fourth with Count Dracula and the Wolf Man, was a commercial success, but was one of the last Universal movies featuring Frankenstein's monster, vampires, and werewolves, with the exception of the comedy "Abbott and Costello Meet Frankenstein" (1948), in which all three appear. Creighton Tull Chaney (February10, 1906 –July12, 1973), known by his stage name Lon Chaney Jr., was an American actor known for playing Larry Talbot in the 1941 film "The Wolf Man" and its various crossovers, and Count Alucard (son of Dracula) in numerous horror films produced by Universal Studios.  He also portrayed Lennie Small in "Of Mice and Men" (1939).  Originally referenced in films as Creighton Chaney, he was later credited as "Lon Chaney Jr." in 1935, and after 1941's "Man Made Monster", beginning as early as "The Wolf Man" later that same year, he was almost always billed under his more famous father's name as Lon Chaney.  Chaney had English, French, and Irish ancestry, and his career in movies and television spanned four decades, from 1931 to 1971.
