How to open a QT movie programmatically?

What you added in the last message looks about as good as it gets. As 
in, I don't know how, because I don't think that works.

SophieQuickTimeMovie class >> example example2 example3

has a simple solution to that question, which I can see you've found. 
But it doesn't work. Running the Tests for Sophie shows some stuff is 
broken.

I gave up trying to open a movie with code in a Workspace, and decided 
to learn from what works, which is to open the Macbeth example file. 
That shows a Tweak-managed infinite loop ( [self isMovieDone] 
whileFalse: in SophieQuickTimeAudio>>playMovieScript) running between 
SophieMovieFramePlayer and SophieQuickTimeMovieViaPlugin. The Player has 
the buttons. ViaPlugin accesses QuickTime on the Mac.

I'm still in the middle of digging out details about Tweak and 
#startScript: before I go back to that part. It's lead me down an 
AsyncScriptMessageSend rabbit hole. If  you want to freak yourself out, 
open the ProcessBrowser. Freaked me out.
