Unstoppable turned out to be the last collaboration between director Tony Scott and actor Denzel Washington. Tony Scott died in 2012 and he was the go to guy whenever Washington wanted to make an action film.

The film, loosely based on a real life incident, tells the story of an unmanned runaway freight train carrying dangerous chemicals and heading for a large town and a curvy track.

Denzel Washington and Chris Pine must stop the train or slow it down before it hurts the curve and crashes.

Unstoppable actually starts out rather comedic enough when two inept hostlers move the freight train and mess it up leading to chaos.

Pine is the new newly hired conductor who aids Washington. Rosario Dawson is the person back at the depot who has to lead operations and battle her boss who is thinking about the effect this will have for his company's bottom line.

Scott is the type of director who learned how to deliver such an action film. He did have a few duds in his time. The story might be a little dicey here and there but he gives us a well paced solid thriller.

UNSTOPPABLE, Tony Scott's final movie before his suicide, is a great swansong from the director. It's very much in the spirit of his previous output, in that it's a straightforward action-thriller, stylish, fast-paced and entertaining. It's very much like SPEED but without all that 1990s-era cheesiness that has dated that movie

Of course, runaway train movies are nothing new, but this one ticks all the boxes. It has interesting central characters (Denzel Washington can near enough sleepwalk through these parts now, but that doesn't make his acting any the less enthralling, while Chris Pine is much better than he was in the overrated STAR TREK) and a dynamic relationship filled with realistic repartee. There's a high level of engaging technical detail that makes the plot feel true to life, despite the bombastic nature of its more out-there action bits.

Strip away any kind of sentimentality, add in a pulsing soundtrack and some great set-pieces, throw in plenty of suspense and tension and top it all with Tony Scott's dynamic direction....yeah, I think this is one of his best, up there with ENEMY OF THE STATE and CRIMSON TIDE, and much better than the slightly lacklustre TAKING OF PELHAM 123 remake which preceded it.

Will (Chris Pine) is a new engineer, and Frank (Denzel Washington) is a veteran driver. After some incompetence, a big train gets loose and runs away. Will and Frank try to chase down the train with their own locomotive.

It is a simple action thriller. Director Tony Scott is an expert in the action genre, and he puts all his skills to work here. There is a lot of fun train action going on in this movie. The CGI is pretty good, and blends in very well with the real world. There is some character background stories, but they're just the side dish. The main course is the action, and it's one continuous series of action scenes after a quick intro.
