Since this movie has a really solid reputation, I was really eager to check it out. First of all, it is too bad that I saw before two really weak remakes ('Body Snatchers' and 'The Invasion'), without mentionning the countless copycats such as 'The World's End', as they slightly ruined the story for me. I mean, right from the very start, I already knew how the whole thing was going to play out and, as a result, it didn't have such a huge impact. Still, it must have been pretty neat to see this movie in the 50's, when the formula was completely new. Furthermore, I wish they didn't force Don Siegel to add an introduction and this happy-end because the movie, above all with a bleaker ending, would have worked better. Still, it is a really solid horror flick, terribly effective and entertaining. Concerning the actors involved, to be honest, I didn't care much for Kevin McCarthy but he was not bad at all but, on the other hand, I was quite mesmerized by Dana Wynter who was simply quite gorgeous to look at. To conclude, even if it is 60 years old, it still works fine, it is a classic and it is definitely worth a look, especially if you like the genre.
