'Alfred Hitchcock Presents' is a very interesting and very well done, if not consistent, series that ran for seven seasons between 1955 and 1962. Every season had some truly fine episodes, and they all had some not so good episodes. This was all obvious in Season 4, that had some real highs and some real lows and sometimes in quite quick succession to each other. Arthur Hiller's episodes did vary, with none of them really being misfires while with no series high points.
He did direct some season high points though, and "The Morning of the Bride" is definitely for me in the better half of Season 4. By all means, it is not one of the best 'Alfred Hitchcock Presents' episodes but it is one of Hiller's best episodes ("Post Mortem" also being one of his best). "The Morning of the Bride" is not quite perfect, but it is a great episode and another great representation of series favourite Barbara Bel Geddes. Making the most of an intriguing premise.
Maybe it is a little bit of a slow starter.
Otherwise, "The Morning of the Bride" is great. Bel Geddes' performance is not quite as amazing as her tour de force performance in "Lamb to the Slaughter", but it is still truly excellent (very powerful in capturing her character's suffering and vulnerability). Even better is a truly terrific Don Dubbins, really unsettling as the character that grows the most. The chemistry between them scintillates. Hitchcock's bookending is amusingly ironic and Hiller directs with more confidence and edge.
Furthermore, it's solidly made with some atmospheric photography. The series theme music is one of the best and most inspired examples of pre-existing classical music being used as a main theme, fitting perfectly with the series' overall tone. The writing is thought provoking, fun and unsettling, with no over-talkiness and there is a good deal of intrigue and dark suspense. The ending is well executed and interesting, if not one of the series' most ingenious.
In summary, great. 9/10.
