Warner's dvd of THE GREAT ZIEGFELD (1936) has an overture and intermission...can't quite remember off the top of my head if there is exit music (but I think there is).
THE COWBOYS also contains Intermission, Entr'act, and Exit Music. FOR WHOM THE BELLS TOLL contains only the Overture (minus the photo-montage on the LD).
I think I remember that MAD WORLD DVD has the intermission and exit music, but not the Overture.
For initial screenings, Warner's SGT, YORK, ADVENTURES OF MARK TWAIN and RHAPSODY IN BLUE had Overtures. The Rhapsody in Blue Overture is included on a Warners CD of Gershwin music from films.
I produced the Lser of 1776 and the Overture is not bogus, but edited from notes left by conductor Ray Heindorf. we did make up an intermission music as the restored version of the film was now three hours. All this was done with the directors permission and encouragment.
The Boyfriend - Intermission Can Can - Overture/Intermission The Love Parade - Exit Music Mame - Overture One Hour With You - Exit Music Raintree County - Overture/Intermission Showboat ( 1929 ) - Exit Music and Tom Sawyer ( 1973 ) - Overture/Exit Music. ( Does the new DVD have these extras? )
I saw LION OF THE DESERT, BLACK SUNDAY 1977, and they had intermissions, but the DVD didn't. When REDS, BARRY LYNDON, RIGHT STUFF, GODFATHER 2 played on HBO in the early 80's, they had intermissions, but not sure if the theatrical version, nor the LD/DVD had them either (the screening for GODFATHER 2 I attended in 83 didn't).
I don't recall the laserdisc of "Mame" having an overture, unless you count the music during the opening credits.
The new "Tom Sawyer" DVD does not have the overture that was included on the laserdisc version.
I saw "Black Sunday" during its theatrical release in 1977 and don't remember an intermission. With a running time of less than 2 1/2 hours, an intermission would be unlikely.
I recall "Reds" and "Barry Lyndon" having intermissions during their original theatrical runs but not "The Right Stuff" or "Godfather II."
The original four hour version of "Heaven's Gate" which I saw in NYC in 1980 (the abbreviated one week run at the Cinema I before it was pulled from release for recutting) included an intermission. The DVD features the original cut; I don't know if the intermission is included on the DVD.
Both Reds and Barry Lyndon had intermissions during their original theatrical run.
I guess it was left up to some theatres whether or not include an intermission. I saw Gandhi twice during its opening week run in 1982 at two different theatres. One theatre included an intermission (which is duplicated on the laser disc) and the other ran it without an intermission.
My sister saw Titanic during its opening run and there was an intermission which is something I'm sure Cameron never intended. I guess the theatre needed to sell more snacks.
How to Marry a Millionaire has Alfred Newman conducting the lenghty "Street Scene" overture. Newman and the 20th Century Fox Symphony Orchestra also reappear onscreen very briefly at the close of the film, reprising a bit of the opening credit's score.
I think perhaps in Europe, it is (or was) more common to have intermissions in film of any length than the U.S.A. In America, Where Eagles Dare was shown without intermission but British filmgoers have verified that it was shown in Britain, at least, with an intermission and entracte which was duplicated on the laser disc but eliminated from the DVD.
I suspect The Cowboys overture, intermission and entracte are also from an overseas print. The laser disc of Blake Edwards' The Wild Rovers also had an overture, intermission card and entracte which it never did in its U.S. run.
"Chitty" doesn't have a musical overture prior to the opening credits, but it does have an extended audio-only sequence before the opening credits featuring the sounds of racing car engines. Omitted for broadcast and cable showings, this is included in the wide screen DVD edition.
Also, "That's Entertainment Part II" had an overture that was featured in the original NYC and LA engagements but eliminated in the national release. The overture was included in the DVD released last year.
