Before I begin, I'd like to say what an impressive amount of time and effort you've devoted to your site.  This is, quite possibly, one of the most professional non-professional sites ever created for an entertainment franchise.

I hesitate writing to you, but I need to clarify certain aspects of your previous posts for BTTF 4.

The facts:

1. I understand the anxiety of not knowing anything about a film project.  The Total Film bit was erroneous in its claim that Ed Solomon is working on a BTTF project involving Roswell 1947.  Its inclusion of Sarah Michelle Gellar should also tip you off to its questionable character.  However, it's not all wrong.  Yes, Mr. Solomon is hard at work on feature film treatments for Amblin Entertainment and Universal. Basically, he's been commissioned (not contracted) to show the viability of expanding the Back to the Future franchise.  There are several other writers doing the same thing for other Universal-governed franchises. It's part of an in-house development project that's been going on since November of 1998 (e.g. Quantum Leap).
2. These are treatments, not scripts.  This means that the project that Mr. Solomon is developing presages the pre-production process.  I want you to understand that.  Just because there are BTTF projects in consideration, I don't want to give you the impression that they're in active development.  Currently, the idea is to have a Back to the Future 4 and Back to the Future 5.
3. As for casting, Gellar's name was thrown out by an excited fan, no doubt.  Characters, settings, etc. are so malleable at this point, casting is actually laughable.  In fairness, Mr. Solomon is only including the characters of Doc Brown and Clara from Back to the Future III in his treatments.  The other characters are unknown to anyone but Mr. Solomon, to be honest.
4. The deadline for his treatments is June 14, 1999.
5. There was never a Back to the Beginning script.  That script was another fan's idea and is in no way related to Amblin.  The only BTTF-related scripts officially owned by Amblin Entertainment are the three feature films and the animated episodes.  And judging from the synopsis given, I don't think Amblin would have shelled out the bucks for an 11-year-old Marty McFly and a homeless woman.  No hook, no sci-fi twist.
6. Best case scenario: the films premiere in the second quarter and fourth quarters of 2001.  This isn't far off base, but you have to understand something: whatever the Universal Powers-That-Be deem the most viable project (which could be Magnum, P.I. or Quantum Leap), that project will be placed on the fast track.  Most likely, the other projects will dissapate.  This could very well be the future for BTTF4 and BTTF5.  Who knows?
7. There's another writer lined up to work on BTTF4/5, but I don't know his/her name, nor his/her capacity on the project.  To be honest, Ed Solomon was working on this project as sort of a "side job."  It's not an official project, you understand.  That's why — as you well know — things are very nebulous and facts are hard to find in the realm of BTTF.  Men in Black (keeping in Ed Solomon territory) had seven writers before him working on treatments, but you'll never, ever hear who they were.  Some surprising names.

All I can tell you is that Universal — thanks in large part to your site, to be honest — is looking into bringing the BTTF universe back to the screen.  Waiting for films is frustrating.  There are so many great films in the pipeline that never make it through, if you ask me.  Star Wars might be vying for the all-time highest anticipation rate, but folks like you bolster enthusiasm for my job.

I have no information regarding the involvement of Mr. Zemeckis, Mr. Gale, nor Mr. Spielberg.  Right now, these are all the facts.  I don't think we'll know anything new until late June, early July.

Keep up the excellent, excellent work.  It's simply a superb site.
