Brendan Gleeson might be one of the most underrated actors in the public eye. I didn't know anything about this movie when I rented it to watch it, so I had no idea who the director is. Reading it now, it makes sense. The movie is really skillfully done, the performances are great and even when you think you know where this is going, it might still be able to surprise you.

There were a few moments where you think "well he could say this or do that" to prove a point. But that is not what the movie is trying to tell you/do. The movie cares about the characters, but even more about society and how we ourselves play a role. A role that might not even befit us, but under normal circumstances we would never change ourselves. Why should we, we are happy as it is, aren't we? These questions and a lot more are being transported via a mystery story, that really has some punches for the viewer. I also really liked where this went at the end, but that is up for discussion ... Watch it and I'm sure most of you won't find this boring at all

This film begins with a wealthy architect named "Liam O'Leary" (Brendan Gleeson) who is having some financial difficulties concerning a speculative purchase on some land he has recently financed. In addition to that, he is also having some martial problems with his wife "Jane O'Leary" (Kim Cattrall). So things aren't going as smoothly as he would like. It's during this time of stress that he begins to have what his friends consider to be hallucinations when he tells them that a man who looks exactly like him keeps appearing at irregular moments. To make matters even worse, he becomes convinced that this man intends on harming him for unknown reasons as well. Now rather than reveal any more I will just say that, although this film is billed as a comedy, I really didn't see much humor in it at all as it was more of a mystery-drama than anything else. In essence, this was a rather peculiar film which had some dull scenes here and there yet managed to keep my attention for the most part and for that reason I have rated it accordingly. Average.

I'm not sure whether this movie was good or not, but I kind of liked it. It was peculiar, but in a good way (not like Solondz's Wiener-Dog I saw recently).

The "Celtic Tiger" part was of no relevance to me - I wouldn't know whether it portrayed 2006 Ireland accurately or not; I was viewing this movie as a regular stalker flick, and, as such, it was quite engaging.

The acting was good, especially by the lead male. Kim Cattrall's role was not a major one, so her accent didn't bother me, especially since everyone in the movie had sort of a "neutral" accent. Having been to Ireland, I can say that none of the people in the movie sounded like the natives I met on my trip to Ireland.

The set-up was very good and engaging, but the movie declined significantly upon the doubles's entering the protagonist's house. There is no way something like this would happen in real life. It was just not believable. I was also sort of offended by the way they chose to portray the wife - as though they were trying to say that women are generally dumb and shallow, and the only thing they care about is for a man to pay attention to them. This is inaccurate and there is no way a wife would mistake a stranger for her husband of many years. Perhaps they were meant to imply that Jane knew all along that it was the double (if so, I must have missed it),in which case, perhaps, I would have seen it differently.

The ending was also kind of weird, but very original and somewhat satisfying and thought-provoking.

All in all, an enjoyable movie, and definitely superior to many a stalker flick I've seen lately. Would recommend.
