Howdy. I'm not sure if my other message was posted so I'll repeat the info.
Larry Harman (A.K.A Bozo the Clown) currently owns US rights to almost all
of the Soviet cartoons from 1945's Wedding Under the Coral Sea thru the
late 50s.
  Harman gave new titles to these films (sometimes releasing the same film
under two differant titles!) and syndicated this all-color package to
TV in the early 60s. Sometimes you can find these 16mm prints floating
around the collector's market- almost always beautiful Kodachrome prints.
 THey all have a strange end title stating the film has been approved by the
 U.S. military! Guess they wanted to make sure none of that red poison
snuck into any kiddie films. Some of the animation in these shorts is
amazing. Wedding under the Coral Sea (official films released this in
b/w as UNDERSEA WEDDING) even features some rotoscoping from live action.
 I believe Harman re-issued many of these in a new TV package a few years
back- I'll have to check to see. Sterling Films of England also had a handful
of Soviet cartoons (again, retitled of course) they distributed in the mid
 50s on 16mm- mostly rental prints.
 RE: films with projections/ projectionists-
 THE BLOB ('58) Features they slimey critter oosing out of a projection
booth. Look close and you'll see a quick shot of a Century projector.
 I Have a strange cartoon called FINDING HIS VOICE (1929) produced by
the Fleischer studio for RCA's phonofilm process. It features two strips
of film learning (in great detail!) about how sound on film works. This is
a lot of fun- the instuctor seems to have a problem reading his lines! One
on the neatest things here (to me, at least) is the Simplex projector and
RCA soundhead shown (In drawn form!). I had purchased a late 20's
Simplex Standard head with a RCA soundhead a few years before, and it was the
same as in the film!
 I run a small mail order video company called SNAPPY VIDEO (Insert plug\
 here) that specializes in rare 1930s cartoons- FINDING HIS VOICE is
available on CULTOONS! volume 4 (a collection of educational/promotional
and theatrical cartoons).
 I can lend out my 16mm print of this short if you wish to run it- The
sound is slightly off sync, however.
 That's all for now- bye kids
