Following on from Greg's comments on the Xanadu viewing, i do like 8mm films for the edited versions of features, it is very unique and, as in the case of Xanadu, can make a so so film much more viewable, or at least, turn a cinema flop into something viewable and fun.
Xanadu is one of top titles in that league, others i think could include,
Helter Skelter, (the original TV movie was three hours long), this Iver release covers the story very well in 30 minutes,
Saturn 3, the feature is quite long drawn out, so this 400ft version packs in the story, the only down side to this title is the lack of an end title.
Star Trek The Motion picture. On this one you have to be a real trek fan to want to sit through the full feature, this 45/50 minute cut down is fairly good despite some of the crappy editing by Marketing.
The Exorcist, while not a bad feature, (for those who like the film) the 3 x 400ft version packs in the story very well, ours has the few extra parts that were in the 400ft version edited into our 3 x 400. The editing of this film is, in my opinion very good.
Who Dares wins, this 600ft version is very well edited and again, makes a long film a much better viewing. The feature isn't a bad movie, its just very long. As everyone in the hobby knows, the digest or mini features allow us all the unique chance of viewing many movies in one showing. It may not be the way the film makers want their movies viewed, but singling out the makers of Xanadu, they should be thanking U8 for making one of the worst movies into a watchable fun reel.
I know there are many in the hobby who will only collect features but it think the min features and shorts are one of the best parts of the hobby, clearly, with new releases selling, they still are.
