Usually known for being an actor and comedian, Dudley Moore was also a pianist and composer, and this movie was one of the half a dozen films he actually composed the music for.
Dudley Moore passionately stated on numerous occasions that composing the score for 'Six Weeks' (1982) was among the most satisfying and fulfilling experiences of his professional life, and often featured a suite of its themes in his concerts.
Scenes from William Christensen's production of "The Nutcracker" can be seen in this movie and apparently this was one of the first pictures to do this.
This movie represents the star-teaming of its two leads, Dudley Moore and Mary Tyler Moore, who shared the same surname that of Moore. The same last name aspect was used as a gimmick for this movie's marketing.
