Context: Rhett Butler is a fictional character and one of the main protagonists of "Gone with the Wind" by Margaret Mitchell. George Ashley Wilkes is a fictional character in Margaret Mitchell's 1936 novel "Gone with the Wind" and the later film of the same name.  The character also appears in the 1991 book "Scarlett", a sequel to "Gone with the Wind" written by Alexandra Ripley, and in "Rhett Butler's People" by Donald McCaig. "Frankly, my dear, I don't give a damn" is a line from the 1939 film "Gone with the Wind" starring Clark Gable and Vivien Leigh.  The line is spoken by Rhett Butler (Gable), as his last words to Scarlett O'Hara (Leigh), in response to her tearful question: "Where shall I go?  What shall I do?"  Scarlett clings to the hope that she can win him back.  This line is also partially spoken by Rhett Butler in Margaret Mitchell's novel "Gone with the Wind", published in 1936, from which the movie is derived. Boston University Academy (BUA) is a private high school operated by Boston University.  Founded in 1993 and located on the Boston University campus, the Academy is geared toward college preparatory work.  As part of its integration with the university, students are able to take college courses for credit their junior and senior years, and are guaranteed acceptance to Boston University upon maintaining a 3.0 grade point average in Boston University courses. Rhett is the official costumed mascot of the Boston University (BU) and the Boston University Academy (BUA) Terriers.  The Boston Terrier has been the BU mascot since 1922.  The often snarling, bi-pedal black and white Boston Terrier was later named after the male lead in Margaret Mitchell's "Gone with the Wind", because "No one loves Scarlett more than Rhett" referencing Rhett Butler's affection for Scarlett O'Hara (scarlet is BU's primary color).  In recent years Rhett has frequented Boston University games, events, and dining halls wearing his scarlet and white double-zero hockey jersey.  Other outfits include a basketball jersey and a referee uniform (typically worn during the short youth hockey games that take place during ice hockey intermissions).  However, he is also known to enjoy wearing his scarlet superhero cape when the occasion presents itself.  Like all mascots, Rhett and the Terrier logo are ubiquitous at athletic events.  The Terriers play varsity Division I intercollegiate sports in ten men's and twelve women's programs.  Rhett's nemesis is Baldwin, the Boston College eagle. Scarlett is a 1994 American six-hour television miniseries loosely based on the 1991 book of the same name written by Alexandra Ripley as a sequel to Margaret Mitchell's 1936 novel, "Gone with the Wind".  The series was filmed at 53 locations in the United States and abroad, and stars Joanne Whalley-Kilmer as Scarlett O'Hara, Timothy Dalton as Rhett Butler, and Sean Bean as Lord Richard Fenton.  The miniseries was broadcast in four parts on CBS on November 13, 15, 16 and 17, 1994. Gone with the Wind is a 1939 American epic historical romance film adapted from Margaret Mitchell's 1936 novel of the same name.  The film was produced by David O. Selznick of Selznick International Pictures and directed by Victor Fleming.  Set in the American South against the backdrop of the American Civil War and Reconstruction era, the film tells the story of Scarlett O'Hara, the strong-willed daughter of a Georgia plantation owner, from her romantic pursuit of Ashley Wilkes, who is married to his cousin, Melanie Hamilton, to her marriage to Rhett Butler.  The leading roles are portrayed by Vivien Leigh (Scarlett), Clark Gable (Rhett), Leslie Howard (Ashley), and Olivia de Havilland (Melanie). In Margaret Mitchell's novel "Gone with the Wind", Twelve Oaks is the plantation home of the Wilkes family in Clayton County, Georgia named for the twelve great oak trees that surround the family mansion in an almost perfect circle.  Twelve Oaks was described as a "beautiful white-columned house that crowned the hill like a Greek Temple," having true southern charm and whimsy.  Margaret Mitchell came up with the idea for The Twelve Oaks, and modeled the home after an actual antebellum mansion located in the historic area of Covington, Georgia.  The home that was portrayed as Margaret Mitchell's Twelve Oaks in the film "Gone with the Wind" has been renovated and is now open as a bed and breakfast and event facility in Covington, Georgia, thirty minutes east of Atlanta. The Boston University Terriers are the ten men's and fourteen women's varsity athletic teams representing Boston University in NCAA Division I competition.  Boston University's team nickname is the Terriers, and the official mascot is Rhett the Boston Terrier.  The school colors are Scarlet and White.  The mascot is named Rhett after Rhett Butler from "Gone With the Wind", because "no one loves Scarlet more than Rhett." Katie Scarlett O'Hara is a fictional character and the main protagonist in Margaret Mitchell's 1936 novel "Gone with the Wind" and in the later film of the same name.  She also is the main character in the 1970 musical "Scarlett" and the 1991 book "Scarlett", a sequel to "Gone with the Wind" that was written by Alexandra Ripley and adapted for a television mini-series in 1994.
