Do you have the 60s film "The Little Shop of Horrors" or the 1986 musical comedy "Little Shop of Horrors". If it is the musical comedy, please tell me where and how you found the film with the alternate ending, because I do enjoy the Broadway version where Twoey wins much better than the film. The musical comedy of the film originally allowed Audrey II to win and take over the world. However, it was shown to test audiences who did not appreciate the death of the main characters, and so the ending was changed to have Seymour kill Audrey II and live happily ever after with Audrey. The alternate ending still exists and can be seen on Youtube, but only in black and white. The color version exists but I believe only the director has a copy of it and refuses to release it.
I Got the alternate ending by buying a blu ray Director's cut, the version on the director's cut comes with a fully restored alternate ending, in full color too. and yes, it has everything, and is just as long as the youtube version, including when it says "The End?!?" on the screen and Audrey II comes out of the screen and eats the camera, just only in this one, the "The End?!?" appears ontop of the scene with Audrey IIs ontop of the statue of liberty, but another difference is that the song is fully restored, and the sound effects are restored too, but also other music tracks and sound effects missing from the scene before the final number are restored too
