I wonder if there are collectors on here that have taken the editing scissors to more than one version of a title to splice in
added scenes into an edited condensation, or in some cases a feature.

I haven't personally, Hugh. But I have a 1200ft Star Wars reel. The previous owner skillfully cut the 200ft extracts into the 400ft digest, spliced on the 2 x 400ft Empires Strikes Back and added a credit sequence at the very end using the end of the 200fter I guess. It works well.

Hi Jon, well done on the Star Wars , you lucky little devil you, but I've added scenes to a few features, like the Chas. Bronson film
"Breakout" which I had to put in a very important sequence, the bad guy being sliced & diced by the propeller, on show in the 400'
but not in the Opt, nor the drop of the Mexican in the prison raid. I've many I can quote from Universals Horror/Castle, to the foreign
versions, plus features. The German versions of "Star Wars" have different scenes to splice in too.

I've got Superman 3x 400 that also has the 400ft excerpts spliced into it to make even a little longer and now completely fills a 1200reel.

This was done before I got it but I have used my own handy editing chopping table on a few occasions,not least for the Derann "selected scenes" 2 x400ft release of Carrie.
Quite a random viewing when first seen as released.
Put it all in order and you really do have a creditable mini feature with still a decent standalone storyline running completely through it!

It's a bit like a Tony Hart creation...not a Scooby Doo of what it's going to be when it starts off, but by the end, after the camera zooms out, hey presto..a lovely beach scene c/w Palm Trees!

I have done it several times. The exellent Mountain King Kong with the missing scenes added from the awful Nostalgia Merchant copy. Several silent comedies like Chaplin's The Count and A Night Out(Blackhawk-Walton) Ben Turpin's The Daredevil (Blackhawk-Film Office). Raoul Walsh's The Wanderer(5 reels) with added scenes from The Feasts of Ishtar(1,5 reel) for a more complete 6 reeler. Disney's wartime shorts Seven Wise Dwarfs and All Together,longer versions made from two different copies of each. Mack Sennett's two reel comedy Love in a Police Station from a one reel cutdown plus "Joyriders". The first episode of The Adventures of Captain Marvel (three reels) by mixing the two reel versions of Ivy and Derann, etc etc

Panayotis, Which print was the best. I have the Derann release.

Definitively the Ivy print! Ubfortunately, for the rest of the episodes I bought the Derann prints because they were cheaper. They are not bad at all but,in comparison with Ivy,it shows...
