Incidentally, I am currently working on a fan edit / mashup of The Menagerie and The Cage, with my idea being to present it as though it were a theatrically released 'movie' from 1966 ala the way the Adam West version of Batman had a theatrical film that was more or less in complete continuity with the series, and came to theaters between seasons. This mashup includes new 1960s style movie titles and end credits to more fully sell the concept of it being a movie outside of the series (but within it's continuity), as well as featuring more of the footage excised from The Menagerie but present in The Cage, cropping it to letterbox ratio to give it a 'released in theaters' feel, and adding in a few other features to make the whole thing feel more theatrical and big, such as select effects shots from other episodes (including some of the alternate establishing shots of Starbase 11 from "Court Martial").
The project is pretty much for my own amusement and is about 30% done at present, but I'm enjoying the process of editing it together so far.

It really feels like it could have been released this way originally. Maybe the lure of it being a theatrical movie might have enticed Hunter back to reprise Captain Pike in a bigger guest role than the character-in-a-chair-going-beep we get in the original?
