Here is the original 1975 trailer for Stanley Kubrick's "Barry Lyndon", widely acclaimed by critics as one of his best films. Although highly acclaimed, it wasn't financially successful at the time due to the extravagant production costs. Some critics griped that it was too slow moving, but that's the beauty of the production. Most of the critical establishment hailed the film, some calling it a masterpiece. In the comments section, a viewer notes that the trailer contains some differences from the final release version. This is probably true, as trailers must be released long before the finished film and Kubrick was known to make changes in his films almost up to the moment of release.
