Review: This for me was a wonderful introduction to the talents and beauty of Marion Davies. She is not only gorgeous but hilarious in this film. (I believe that Lucille Ball may have modeled her later career on Davies' style, that could be termed "zany beauty".) Vidor's direction is light but sure-handed, the story is a chestnut of course but the acting is marvelously contemporary, and the star-watching element for fans of the silent era, with many cameos, adds to the overall fun. It combines the elements of slapstick with adult drama and good old timeless romance quite well. For all movie fans who have a knee-jerk reaction to watching silent films, sit through this one and it may change your attitude. Question: is it a negative review?

Review: I think this is almost all I need to say. I feel obliged to explain my actions though. I've basically never seen such an armateur production, and I mean that in all senses of the word. Although the physical camera work, boom MIC operation and other technical aspects of this film are laughable, unfortunately its not the only areas.Unlike some classic independent films that have been saved by their scripts great characterization and plot, this unfortunately has an awful script, awful acting and worst of all, awful annoying characters.It's a crime that for the every independent film that gets, distribution like Haiku Tunnel, there's a 101 other indie films that died silent deaths. I don't know who the Kornbluth brothers know at Sony, but that can be my only explanation as to how this amateur family production ever got distribution. I'm quite bemused as to why they picked this up.The ONLY part of this film that holds out any intrigue is its title. However, the reason for that is even a let down. I hope this review will save a few people that may be intrigued by this films title from going to watch it. I've seen a lot of films in my time, and I'm very forgiving when in the cinema, but this was too much. I'll never forget 'tunnel', for marking an important point in my life experience of cinema. Shame it's such a low point. Question: is it a positive review?

Review: Director Vincenzo Natali's Cypher is a complex and imaginative thriller which, although requiring some suspension of belief and plenty of concentration, manages to be a thoroughly entertaining experience.Morgan Sullivan (Jeremy Northam), a stay-at-home husband with an overbearing wife, decides to add a bit of spice to his mundane existence by getting a job as an industrial spy at high-tech company Digi Corp. His job is to travel to conferences across the country (under the assumed identity of Jack Thursby) and secretly broadcast the speeches given back to his bosses, via a nifty little electronic pen-gizmo.In reality, however, the speeches are merely a cover for far more nefarious activities. Morgan, along with his fellow conference attendees, is being brainwashed. The drugged water they are drinking puts them into a temporary coma, during which they are told to forget their pasts and permanently adopt their new identities. Once they are totally convinced that they are someone else, they are told to apply for jobs with rival companies, where they are able to indulge in corporate espionage without suspicion.But Digi Corp's plans are scuppered by the intervention of shady operative-for-hire Rita Foster (Lucy Liu), who opens Morgan's eyes to what is really happening. She gives Morgan an antidote to the mind altering drugs so that he can resist the brainwashing techniques. She also warns him that if Digi Corp suspects that he does not fully believe he is Jack Thursby, then he will be 'eliminated'. Morgan plays along, and applies for a job at rival business Sunways.However, arriving at his new workplace, he is given a polygraph test and is immediately rumbled as a spy. Fortunately, the bosses at Sunways see this as an ideal opportunity to feed false data to Digi Corp and Morgan becomes a double agent.From hereon in, things get progressively more complicated; the plot twists and turns and poor old Morgan ends up not being able to trust anyone. In an exciting finale, all eventually becomes clear (but only if you've been following events very carefully).Director Natali handles proceedings confidently and certainly has a great ability to produce a classy looking film for a relatively low budget. He manages to get some great performances from his talented cast; Jeremy Northam,in particular, is fantastichis portrayal of the initially somewhat nervous Morgan is played to perfection.Cypher is another fascinating movie from a director who is willing to take chances and I eagerly look forward to his forthcoming projects, High Rise and Necropolis.
