Just talk so far, but this guy has connections, and a resume, and wants to get it done. http://www.darkhorizons.com/news/30999/a-farscape-film-spin-off-in-the-works
Much as I'd like to see Farscape return, not so hot on the super powered sprog concept. Thing about Farscape is the same as with Die Hard, poor schmuck flung into a situation and trying to do right and hold his own against much greater forces, and going increasingly off the rails whilst rattling through a litany of bluster, bullshit and plans going awry to get through it all.
It's too early for April Fools. And from the sound of things, this project hasn't gone much past the fanfic-writing stage.
