Colour or not, this is a fantastic bit of history to have back after 60 years in which it was believed to be gone forever. I like this quote: "the process is usually one-way: You can’t unthrow a pie."
Here is what has been in existence up until this time. Trivia note: keep a very sharp eye out for a young and thin Lou Costello as one of the boxing spectators.
I know there are others here who are far more expert in the areas of both silent comedies and pie boners, but my reading of Dessem's article and some of the other coverage of this is that most or all of the pie hits are in the footage that's always been in circulation.
The version that AW2 posted has been edited, so it's difficult to tell if the fight was shortened or anything was cut out of the middle. But there is a wipe shortly into the fight which is probably covering missing footage, then later it cuts away then back again and there are lots of additional people who are significantly messier than they were 5 seconds ago. Then the van disappears and comes back again.
But these could also be deliberate time cuts or continuity errors in the original movie. It sounds like Dessem may not have seen the new reel either and the entire article is based around the interpretation of Mirsalis, so who knows?
The pie fight footage has been available, it's the first reel, with the boxing match, that was missing.
My memory recalls a blonde actress slipping on the pie near the end, and that that was a starlet who would become famous. But my memory may be wrong. However, I believe the first woman to take a pie is Anita Garvin, not the woman who slips.
The version on YouTube may not be complete. Collectors over the years often taken frames out of copies of films. That may explain the continuity errors in that YouTube version.
Stan Laurel, who often all but directed many of their films, said of "Battle," "Let's make a pie fight film to end all pie fight films" - that is, to outdo every one made to that point. And they did.
I'm pretty sure the only "good stuff" missing would be where the cheesy wipe occurs at the 8 minute mark. That edit point is most likely from Youngson's "Golden Age of Comedy" clip-show-cum feature from the 60s. Read the entire Slate article and you can get a clearer picture.
The woman who was pied in the butt, then face, then throws a pie at Ollie, misses and hits a fellow's shoes MAY recieve a nice, slowly timed up-close pie (or two?) in the missing scenes. Such action wouldn't have been top "clip show fodder" as the montage of thrown pies Youngson used for his film.
It's really my only hope for any new good stuff from this.
Great to hear the full short is being restored, regardless of any golden pie discoveries.
It's just great to see another tile in the L&H catalogue come back to life. Roach's pictures of the time - particularly Laurel & Hardy- had a frequent WAM element in them - mud, plaster, cooked rice, paint, and certainly pies -- all delivered in generous portions. As a gag man, Stan was about the best there ever was - and the duo was simply great and almost always funny.
Even taking the WAM fet out of this conversation, the rediscovery of said film is a joy to film people. The pie clips we have seen for years all come from what was pulled for inclusion into the aforementioned GOLDEN AGE OF COMEDY. Youngson was know to work cheap, so he only duped what he needed (read: just the money shots), and any title cards, etc. were not copied over from the nitrate elements, which were already pretty well on there way to total decomposition. He just took bits and pieces, so while we are probably seeing everything we want in relation to wam scenes, we are actually seeing a very butchered sequence when it comes to comedy timing and the film itself. This is truly an occasion to be celebrated.
Now if only someone can find a copy of LONDON AFTER MIDNIGHT!
Love you, too
