input: The characters, Jake and Elwood Blues, were created by Belushi and Aykroyd in performances on Saturday Night Live. The name "The Blues Brothers" was the idea of Howard Shore. The fictional back story and character sketches of blood brothers Jake and Elwood were developed by Aykroyd in collaboration with Ron Gwynne, who is credited as a story consultant for the film. As related in the liner notes of the band's debut album, Briefcase Full of Blues, the brothers grew up in an orphanage, learned the blues from a janitor named Curtis, and sealed their brotherhood by cutting their middle fingers with a steel string said to have come from the guitar of Elmore James.  Belushi had become a star in 1978 as a result of both the Blues Brothers' musical success and his role in National Lampoon's Animal House. At one point, he managed the triple feat of being the star of the week's top-grossing film, top-rated television show, and singing on the number-one album within a year. When Aykroyd and Belushi decided they could make a Blues Brothers film, the bidding war was intense. Universal Studios narrowly beat Paramount Pictures for the project. John Landis, who had directed Belushi in Animal House, was aboard as director.  However, the project had neither a budget nor a script. On the former issue, Universal head Lew Wasserman thought the film could be made for $12 million; the filmmakers wanted $20 million. It would be impossible to settle on a specific amount without a screenplay to review, and after Mitch Glazer declined to help him, Aykroyd wrote one on his own.  Aykroyd had never written a screenplay before, as he admitted in the 1998 documentary, Stories Behind the Making of The Blues Brothers, or even read one, and he was unable to find a writing partner. Consequently, he put together a very descriptive volume that explained the characters' origins and how the band members were recruited. His final draft was 324 pages, which was three times longer than a standard screenplay, written not in a standard screenplay format, but more like free verse. To soften the impact, Aykroyd made a joke of the thick script and had it bound with the cover of the Los Angeles Yellow Pages directory for when he turned it in to producer Robert K. Weiss. Landis was given the task of editing the script into a usable screenplay, which took him about two weeks.  The overriding plot premise was unrealistic: religious groups and other not-for-profit organizations are typically exempt from federal or state taxes; although a legislative proposal to tax such property was under consideration in Illinois at the time.

Question: Cooper was born on May 7, 1901, in Helena, Montana to Alice (nee Brazier, 1873-1967) and Charles Henry Cooper (1865-1946). His father had emigrated from Houghton Regis, Bedfordshire and was a prominent lawyer, rancher, and (later) a Montana Supreme Court justice. His mother had emigrated from Gillingham, Kent and married Charles in Montana. In 1906, Charles purchased the 600-acre (240 ha) Seven-Bar-Nine cattle ranch about fifty miles (eighty kilometers) north of Helena near the town of Craig on the Missouri River.

In early 1925, Cooper began his film career in silent pictures such as The Thundering Herd and Wild Horse Mesa with Jack Holt, Riders of the Purple Sage and The Lucky Horseshoe with Tom Mix, and The Trail Rider with Buck Jones. He worked for several Poverty Row studios, including Famous Players-Lasky and Fox Film Corporation. While his skilled horsemanship led to steady work in Westerns, Cooper found the stunt work--which sometimes injured horses and riders--"tough and cruel". Hoping to move beyond the risky stunt work and obtain acting roles, Cooper paid for a screen test and hired casting director Nan Collins to work as his agent. Knowing that other actors were using the name "Frank Cooper", Collins suggested he change his first name to "Gary" after her hometown of Gary, Indiana. Cooper immediately liked the name.  Cooper also found work in a variety of non-Western films, appearing, for example, as a masked Cossack in The Eagle (1925), as a Roman guard in Ben-Hur (1925), and as a flood survivor in The Johnstown Flood (1926). Gradually, he began to land credited roles that offered him more screen time, in films such as Tricks (1925), in which he played the film's antagonist, and the short film Lightnin' Wins (1926). As a featured player, he began to attract the attention of major film studios. On June 1, 1926, Cooper signed a contract with Samuel Goldwyn Productions for fifty dollars a week.  Cooper's first important film role was in The Winning of Barbara Worth (1926) with Ronald Colman and Vilma Banky, in which he plays a young engineer who helps a rival suitor save the woman he loves and her town from an impending dam disaster. Cooper's experience living among the Montana cowboys gave his performance an "instinctive authenticity", according to biographer Jeffrey Meyers. The film was a major success. Critics singled out Cooper as a "dynamic new personality" and future star. Goldwyn rushed to offer Cooper a long-term contract, but he held out for a better deal--finally signing a five-year contract with Jesse L. Lasky at Paramount Pictures for $175 a week. In 1927, with help from Clara Bow, Cooper landed high-profile roles in Children of Divorce and Wings, the latter being the first film to win an Academy Award for Best Picture. That year, Cooper also appeared in his first starring roles in Arizona Bound and Nevada--both films directed by John Waters.  In 1928, Paramount paired Cooper with a youthful Fay Wray in The Legion of the Condemned and The First Kiss--advertising them as the studio's "glorious young lovers". Their on-screen chemistry failed to generate much excitement with audiences. With each new film, Cooper's acting skills improved and his popularity continued to grow, especially among female movie-goers. During this time, he was earning as much as $2,750 per film and receiving a thousand fan letters a week. Looking to exploit Cooper's growing audience appeal, the studio placed him opposite popular leading ladies such as Evelyn Brent in Beau Sabreur, Florence Vidor in Doomsday, and Esther Ralston in Half a Bride. That year, Cooper also made Lilac Time with Colleen Moore for First National Pictures, his first movie with synchronized music and sound effects. It became one of the most commercially successful films of 1928.
