Always likable Tom Selleck is well cast as a mediocre mystery writer (VERY mediocre, based on the samples of his writing we get in the voice-over narrations, which are one of the funniest parts of the movie). He's looking for a plot for his next book and finding it in the person of a beautiful Romanian college student (Paulina Porizkova) who seems to be hiding some big secret. The movie plays like the plot of a bad detective book, with perceptions of the female character shifting from dangerous to trustworthy to suspicious and back. The chemistry between the characters works very well romantically as both characters begin to fall in love despite being wary and suspicious of the various goings-on, and the Romanian KGB agents on Paulina's trail make for useful comic villains.

Philip Blackwood is a depressed writer who's lost his spark and his passion for writing. His successful detective character is the subject of endless predictable stories and his agent is on his back trying to get him to turn it around. As he goes to court with the usual oldies who attend in order to have something to Gossip about up steps the beautiful Nina, an eastern European arrested for murdering a fellow countryman with a pair of scissors. Tom Selleck decides to act as her alibi (Hey it's the title of the film as well!) and invites her to live with him as he believes she is innocent. As the police detective that drops by to chat with Philip Blackwood informs him, if the alibi is made up then he is not only a perjurer, but more importantly, he is liable to be the next victim in order for the alibi to stand forever. What follows is a series of ridiculous escapades in which Philip's life is under threat at every stage of the day, never knowing if the lovely Nina is a cold blooded killer or just deadly unlucky.

I had the fortune to get this film out of the video library on a whim and wound up falling in love with the film as much as Blackwood does with Nina, the parallels between his super-cool fictional world and the clumsy long suffering Blackwood are fantastic, and all the supporting cast do a great job.

Don't get me wrong, this is not an Annie Hall or a when harry met sally, it's silly ridiculous and as Farantino says "I gotta say, Phil, You're works a little predictable!" but it's still a good watch and a very fun film.

A lot of us go through our quite ordinary lives daydreaming about being these larger than life characters, so I thought that this story about this sheltered and detached mystery writer, Phillip Blackwood, was quite good because of the funny and endearing way it relates to being a dreamer.

I'm a big Tom Selleck fan, since his days as island hopping P.I. Thomas Magnum, and I think he was the perfect fit for the role of Phil Blackwood. Selleck is this tall, good-looking dude who looks the part of your typical hero or action star, but he is able to come across as this almost goofy, nice guy, and I think those are the qualities that make Thomas Magnum and Phillip Blackwood such great characters. The contradictions between the characters' physical appearances and their personalities make them very easy to like and root for.

I liked the rest of the cast too. Paulina Porizkova was stunningly beautiful and I liked her in her role. The actors who played Blackwood's agent and brother were very funny in their roles.

I recommend this movie. It is lighthearted, funny, and quite charming.
