When you add the original Windows Myst to ScummVM, you usually get a choice of two targets: Myst the game and the movie "The Making of Myst". If you try to run the movie, however, the game will start instead.
This has apparently always been the case. Droid2727 complains about this on irc in 2011, here at 21:18:00, and again at 21:24 here.
When you think that you are telling ScummVM launcher menu to start "The Making of Myst", what you are actually doing is telling ScummVM to launch the first game it can find in the target directory that uses the same engine. In the case of the original Windows Myst CD, it will always be Myst the game, unless you rename or move the MYST.DAT file.
None of the links worked. Another try:
