There are others out there that I know about, but have never seen personally. They exist apocryphally.
*
A Chorus Line was filmed in '76 ("for promotional reasons"). Filmed three different ways, and never edited together, from what I understand. The thinking was it was the only way to preserve the original cast on film for promotional reasons (commercials and talk shows). When Columbia was trying to put together the movie in '82, Michael Bennett wouldn't sell them the filmed material to reconstruct the show; as everyone will recall, he went further, allowing them to use the script and score but not the original choreography in their record-breaking $7.8 million deal. Fearing ACL would be screwed up on film, he wanted to ensure the stage version would never be compromised by film or anything else. The copy of this filmed material that is floating around was apparently a bootleg struck as a reference for those working on the movie by people who were more considerate than Bennett. It was allegedly used along with the book that transcribes the steps (a la Robbins) in reconstructing later productions.
* The OBC of
Hairspray was filmed, at a time when they didn't think another movie would be made. John Waters has a few copies. Reportedly there are plans to release it at some point.
* An alternate version of
Fosse from the commercially released version exists.
* The OBC of
Sweeney was filmed, as was the OBC of
Chicago; while we're on the latter, the revival was also filmed when Ann Reinking was in the cast.
*
Godspell was recorded 12 different times, not including the one at the archives. Quality is apparently really good, but none released. One of them was a professional taping of the OBC at the Broadhurst in '76 for what is now Showtime, never broadcast.
* The recent (2000s) revivals of
La Mancha and
Fiddler were taped.
* Doyle's
Sweeney was filmed in L.A.
* Bette Midler's
Kiss My Brass and Liza's concert at that place on 72nd and Broadway were both filmed. Midler's film was held up release-wise because her Vegas contract prohibited anything new being released on video that could compete with her show, but that may have changed.
* This one is truly apocryphal, as no one has ever confirmed it except for one guy. Before the 2005 film release of
Rent, it looked at one point at the start of the decade as if NBC was going to adapt
Rent for television (presumably to hit back at Zadan/Meron and ABC). The Larsons eventually put the kibosh on this effort. Before they did so, however, NBC filmed a sort of "pilot" version on a large set at SilverCup. The run time was just over an hour; they either cut a lot (which is suggested by the fact that leads got a lot of ensemble material, i.e., Angel led the support group meeting and Collins got Gordon's lines) or only filmed what was absolutely necessary for test purposes. No audience, about three or four sets (looked very cartoonish at certain points, according to one account); the lot looked like the "Over the Moon" set in the movie, and several scenes took place in a bare warehouse-type set a la the one used in the final film for "Tango: Maureen." Also, "No Day But Today" was sung at some point by the cast on a rooftop. They didn't even take the trouble to do any real work, as reportedly the OBC cast recording was dubbed onto the film. There was a big party at SilverCup where they previewed it. Allegedly footage from it has been re-used in commercials for the show, but I don't know. Apparently there are quite a few copies floating around.

Titanic: The Musical and
My One and Only have also been filmed, and were apparently released overseas.
