The DVD of The Hallelujah Trail is 155 minutes long (jacket cover says 159) and has the overture, intermission, entr'acte and exit music.  But it only has an aspect ratio of 2.23:1 (see the scene below taken from the DVD). The black bars on the sides of the same scene at the bottom of this page, give you an idea of how picture information is missing from the original Ultra Panavision aspect ratio of 2.76:1.
