What to say... I suppose everything is still in the speculation stage at this point but, might I remind you that if they have a working script and a budget of 30 mil - that film could be made. It's not a lot of money but think about a film like "Juno" was made for under 10. It could happen. 30 mil. is also in the feature film range of costs. So what, their company hasn't done much - it's all who becomes attached to this thing if it should ever see the light of day.
Disney or Henson could become involved in this - you never know...
The film probably couldn't be made once Disney lawyers jump all over it, thats before even the Henson ones start askin questions and the Henson family have even stopped biographies THEY have been involved with in the past. Seriously, how can you make a Jim Henson biopic without Kermit the Frog. It'd just be an actor picking up some generic frog puppet that doesn't look like Kermit, and him doing a voice that sounds nothing like Kermit.
They would have tried to get Henson involved already if they do want an "official" type biopic but it is standard practice for Henson to comment as well in press releases so we can assume they are not in any way involved, and seriously, they have no hope of Disney involvement unless a) Henson family were involved already, and b) they were prepared to give up a large chunk of that 30 million and control over the film.
Either this isn't going to happen (please god!) or it'd be a generic TV movie that'd probably either be bland, or start muck raking. And i believe a 30 million attached budget doesn't even mean they actually have 30 million, there may be conditions set to that like them getting theatrical distribution or all the permissions they need to do it well.
