As we settled into our seats in Screen One in the Savoy Cinema, Dublin, Ireland, we wondered how on earth Stuart Townsend could exposit the intricate workings of the World Trade Organisation (WTO) to an audience who probably had no idea that it even existed.

We were not disappointed. From the breathtaking opening sequence, to the exhilarating ending, we were on the edge of our seats.

There were some outstanding performances – André Benjamin as Django (from the band Outkast) and Michelle Rodriguez as Lou (best-known in Europe for the TV series 'Lost') in particular were superb as two of the demonstrators. André injected an unfailing sense of humor and light relief into this serious topic, and managed to turn his unusual headgear into a clever statement about endangered species. Michelle gave her character exceptional depth and feeling, and handled a complicated emotional sub-plot with a mixture of both detachment and passion that worked so well on screen.

Charlize Theron played an innocent bystander, Ella, who was trapped in the violent maelstrom, with horrific consequences for both her own character and her character's husband.

During the Q&A with Stuart and Charlize at the end of the movie, an audience member stood up – an employee of the World Bank. She began by saying how cautious she was about coming to a movie about the WTO, but that she had to applaud Stuart for handing such a difficult subject so fairly. Her comments were echoed by a Trade Advocacy officer from a well-known Irish development charity, who congratulated him on creating a movie which managed to be both factually accurate and entertaining.

For anyone who has ever wished that this world was a better place, this movie is a must-see. For everyone else, this is a heart-warming movie about the power of the human spirit to overcome, to work together and to forgive.

(And as a footnote, Stuart gave free passes to the screening to protesters from the Campaign to Save Tara, who are still demonstrating against the construction of a new highway, the M3, in the historical valley at the Hill of Tara in Ireland. Stuart walks his talk.)

This docu-drama about the WTO riots in Seattle in 1999 is made in the same style as "Bloody Sunday", "United 93", and "Battle for Haditha": it just shows events in real time without comment. We follow everyone here from the ground up; the protest groups, the cops on the street, their commanders, city officials, a news reporter, and innocent bystanders. Maybe the scenes with the news reporter are the least fleshed out, but that's a fairly minor complaint for a movie that is very involving and entertaining and thought-provoking. Woody Harrelson and Charlize Theron are very good, as usual, and Michelle Rodriguez is perfectly cast. One of the big surprises here is Andre Benjamin, from Outkast fame, who delivers a fine supporting performance; he's irreverent but very smart. Ray Liotta is very effective as the mayor, and the film does a great job of seeing the complexities in elected officials as he struggles to please all sides; he is looking for the protesters to behave while also wanting the WTO to address important issues.

The audience I saw this with at the Toronto Festival gave it an ovation that lasted all through the credits. In terms of pure audience satisfaction, this movie was up there with "Juno" and "Body of War" and "Eastern Promises" as the fan favorites.

I was lucky enough to see this film in advance, and it opened my eyes to a few very important issues.

Going in, I'd never even heard of the "battle in Seattle," as I was only 13 years old at the time of the protests. But now that I'm aware of the event, it makes me wonder why the controversies with the WTO aren't still being discussed on a larger scale.

This is something that we should all be concerned about, and Stuart Townsend has done us a favor by introducing the issues in a format that is riveting, informative, and inspirational. If there's one thing Battle in Seattle does best, it's that it fires you up to take action any way you can.

Not to mention the great production values, absolutely stellar cast, and intense action sequences (Intense because they're real! Actual footage was used).

I would highly recommend attending a showing of this film with your family and friends, because these matters are important to us all, and Stuart's presentation of them is nothing short of breathtaking.
