"Murder on the Moose Jaw Express," Part One, Scene A

On January 9, 1979, the same as the submission of the Revised Shooting Script for "Supermarket Sweep," and over a year before the first part of the train mystery aired, the Final Draft for "MMJE" came in.  I have already analyzed the Revised Shooting Script for Part Two (from January 22, 1980), and obviously this is an odd mashup, but here goes....

The first thing to discuss is the cast list: 

Note that Scatman's last name would be correctly spelled the following year.  But more amusing is the use of character names from Clue (Mr. Green, Col. Mustard, Mrs. Peacock), six years before Michael McKean would star in that cult movie.

For some reason, my copy of Part Two includes the revised version of Scene A, so I've got three different versions.  Comparing the scripts, the two Scenes A are remarkably similar, although for some reason, the word "pain" would later be capitalized in the boys' slogan.

In the draft, Laverne tells her father, "Pop, it ain't Easter," while in the later version we learn that it's the day before Easter.  Then neither line is in the filmed version, although they did keep Frank saying a little later that they'll be on the train during Easter.
