This movie is based on a very contrived plot device. Van Johnson plays a man who has a peculiar sort of reaction to alcohol--the type you'll only see in movies and I doubt if anyone on this planet does what his character did. While the IMDb summary says he passes out when he drinks, this is NOT the case. Instead, even the smallest taste of alcohol sends him into a fit where he behaves roaring drunk for several minutes--afterwords, he has no clear recollection of his behaviors. As I said, it's contrived--but also odd because the film really isn't exactly a comedy--in fact, much of it is VERY serious. In fact, with a subplot involving racism, the mix is uncomfortable and bizarre to say the least.
On the plus side, the film has very good acting. Van Johnson, despite the material, is excellent and he's given tons of support from the likes of Liz Taylor (who is at her radiant best), Leon Ames (whose speech at the end is terrific), Gene Lockhart (June's father) and Edgar Buchanan--among others. It is clearly filled with quality actors. It's just too bad that the script itself isn't high quality. In fact, it could clearly have used a re-write. It's a B-movie script with A-list actors and production values. Not a bad film but not at all a good one either.
