I'm watching Red Dwarf series 7 for the first time - I'd always avoided it after seeing one awful episode from it (Stoke Me a Clipper) ... it's clearly the worst series for a great show ...
But watching the DVD's extended versions of "Tikka to Ride" and "Ouroboros", which are presented without a laugh track ...
This might as well be Red Dwarf the movie. They're all filmlooked, and only rarely look like video during these episodes due to the single-camera style. There's a flashback and time travel aspect to both episodes that would lend itself well to a movie, and to including clips from previous series ... we flash back to the end of series 6, the beginning of series 1 (to annoyingly rewrite history and include the black hole of comedy herself, Chloe Annett, who sucks the humor out of the series ... but never mind, it'd be a good excuse to revisit series 1 or 8 in the movie) ... Lister's wedding to a Gelf back in ... series 5 I think ... is also referenced.
These being flashbacks, they wouldn't have to look like film, if you kept them brief. You'd have to be carefully choose non laugh track material though ... thankfully the DVDs contain lots of material without laugh tracks as deleted scenes, outtakes etc.
These two episodes do link together slightly, despite Rimmer not being in the latter. The ending to Ouroboros, which is a good one, uses the time travel device from Tikka to Ride.
I think that these episodes and others from Red Dwarf series 7 could be edited together into one coherent story. I think the pace should be picked up a bit, because it doesn't quite work without the laugh track.
Effects shots from previous series could be used in all their filmy glory, and if possible, I'd like to see Holly brought back somehow. You'd have to keep Rimmer in the story too somehow.
You'd also have to crop the 4x3 footage to 16x9, and sort of rework the order of things, introduce the plotlines of all the episodes you're using together at the beginning of the film.
But it would definitely work. It's halfway there already.
Just an idea.
