A film reminisent of the olde Saturday Serials in terms of plot and story line. From the opening shot to the clever end, one's attention is raptly held. Robert Downey, Jr's one-liners maintained the light-heartedness, but at the sametime, one could not help but be carried along by his high tech character who never revels his plans, but like the closing is sprung on the audience and the bad guys. Jeff Bridges was a classic as the nefarious alter-ego, evil, minded DR. DeMento type, but with a modern profit driven twist. The perfect evil one that supports the hero of the movie. Action, color, high tech, do-dads, set in multi-locations from the desert to Ironman's lab where he talks to assembly robots. This is definitely a movie that would make a techie breakout in a cold sweat coveting all the gadgets of Ironman. This is a good versus evil film utilizing the homeland security theme. For those of us as kids who used to sit on the edge of our seats during the Saurday Matinees watching the serials, we again are put on the edge of the seat. Grab a corn, pop and be prepared to be entertained for 2 hours and 6 mins. The story and acting is good enough to hold you for that long. I predict a sequel...clue is in the final ending line.
