After a life-changing experience, a billionaire playboy decides to utilise his wealth and the array of technology at his disposal to protect the innocent. Sound familiar? Rest assured, any similarities to a certain Dark Knight end there.

In Iron Man, our hero is Tony Stark, a billionaire playboy and hard-drinking, womanising weapons manufacturer as played by the brilliant Robert Downey Jr. Undoubtedly, his performance is the centrepiece of the film, with his dry sarcasm and unflappable resolve working like a magnet to draw us into the filmin.

We have no problem investing in the characters because Iron Man is strongly grounded in reality, and has been a phenomenal success worldwide for this very reason - even those not normally too keen on superhero movies can enjoy it.

The plot, while retaining all the elements of the standard superhero origin film, has quite a few unexpected twists and turns (be sure to stay until after the credits for an additional scene featuring a familiar face). Stark, for one, isn't exactly what you'd call superhero material, but neither is the impressive supporting cast of Oscar nominees and winners in Terrence Howard, Jeff Bridges and Gwyneth Paltrow.

The film succeeds because it knows exactly what it wants to be - a summer popcorn flick - and as such, the resulting effort is one of the most enjoyable comic book adaptations ever.

Simply put, Iron Man is fun on every level - and how often have you been able to say that of movies lately?

Andrew (Caine), an ageing writer, has been left by his much younger wife. She has left him for a much younger man, an actor named Milo (Law). Keen to size up the man he has been left for, in every way imaginable, Andrew invites Milo to his country estate, under the pretence of making some kind of peace, and involves him in a crooked plot to test the young suitor's mettle.

This version of Sleuth is unashamedly a vanity project for all the creative folk involved. Kenneth Branagh directing Jude Law and Michael Caine in a Harold Pinter adaptation of Anthony Schaffer's play. At least it's an entertaining Vanity vanity project and a movie that is quite different to the original 1972 film version of the same play, which also starred Michael Caine, though in the opposite role (literally, there are only two in the movie). Whilst the (near flawless) original was a carefully paced and well-planned thriller, this adaptation is a stripped-back, rather frantic, and more intellectual movie. Sleuth is a tense 80-odd minutes that you are unlikely to regret having spent in the theatre.
