The Ladies of Grace Adieu and Other Stories, published in October 2006, is a collection of eight short stories by Susanna Clarke and illustrated by Charles Vess.  The stories, which are sophisticated fairy tales, focus on the power of women and are set in the same alternate history as Clarke's debut novel "Jonathan Strange & Mr Norrell" (2004), in which magic has returned to England.  The stories are written in a pastiche of 18th- and 19th-century styles and their tone is macabre as well as satirical.  The volume was generally well received, though some critics compared it unfavorably to "Jonathan Strange". Strange Magic is a 2015 American computer-animated musical fantasy romantic comedy film directed by Gary Rydstrom, produced by Lucasfilm, with feature animation by Lucasfilm Animation and Industrial Light & Magic.  The film's screenplay was written by Rydstrom, David Berenbaum and Irene Mecchi, from a story by George Lucas inspired by William Shakespeare's "A Midsummer Night's Dream".  The film stars Alan Cumming, Evan Rachel Wood, Kristin Chenoweth, Maya Rudolph and Alfred Molina.  The score was composed by Marius de Vries and includes contemporary songs, such as "Love Is Strange". David Berenbaum is an American screenwriter most notable as the writer for the 2003 film Elf.  He was also the writer for the film The Haunted Mansion (2003), and the co-writer for the films Zoom (2006), The Spiderwick Chronicles (2008), and Strange Magic (2015).

Directed by Rob Minkoff, the film is written by David Berenbaum and stars Eddie Murphy, Terence Stamp, Nathaniel Parker, Marsha Thomason, and Jennifer Tilly. Often called the most beloved and popular of college fraternity songs, "The Sweetheart of Sigma Chi" was written in 1911 by Byron D. Stokes (Albion, Class of 1913) and F. Dudleigh Vernor (Albion, Class of 1914).  Stokes had written the words while in class one June day that year, and presented them that afternoon to Vernor, who was practicing the piano in a local house, and composed the music at that time.  The song has since become a favorite among ballroom orchestras and was used in two movie musicals of the same name, in 1933 and 1946.  When asked about the song's inspiration, Stokes replied, "The 'Sweetheart' is the symbol for the spiritual ingredient in brotherhood.  It was the Sigma Chi Fraternity itself that inspired the song.  I wrote the words not long after my initiation, and the magic of our Ritual with its poetic overtones and undertones was, I suppose, the source of my inspiration".  The original musical composition remained on campus until 2007 when it was lost and not recovered.
