Some films of this era in Hollywood had reputation of being ''coke movies'' where cocaine was used on the set. Because of this movie's cocaine drug taking subject matter there was at least some small perception that this picture was one of these ''coke movies''.
The film was made in 1981 and first released in 1982 which was about ninety-five years after its source novella 'The Strange Case of Dr. Jekyll and Mr. Hyde' by author Robert Louis Stevenson had been first published in 1886.
The name of the modern medical facility was ''Our Lady of Pain and Suffering Hospital''.
The movie's credits block states that this picture was ''inspired by the Robert Louis Stevenson novel''.
One of the alternate titles of Robert Louis Stevenson's source 1886 ''Strange Case of Dr Jekyll and Mr Hyde'' novella is actually ''Jekyll and Hyde'' which is substantially the same as and similar to this movie's 'Jekyll and Hyde... Together Again' title. Other aka titles of the classic book are ''Dr. Jekyll and Mr. Hyde'' and ''The Strange Case of Jekyll Hyde''.
