Avant le déluge

Almost a decade ago, Leonardo DiCaprio narrated and produced The 11th Hour, which covered the same ground as this documentary. The United Nations designated DiCaprio a "UN Messenger of Peace" in 2014 and tasked him with getting the word out on Climate Change. That is just what he does. Here is a heartfelt, decent and educational documentary about the most important issue of our time: Climate Change.

Filmmakers are intelligent in their use of the biggest asset they have: not only do they keep their movie star on screen, they work hard to tie viewers concern for the environment up with his biography. Leonardo DiCaprio proves his own commitment to the cause; conceding that his own celebrity status draws attention to the topic, but allows the naysayers to say that he is a shallow movie star and therefore this whole issue must be a joke. Though, I have to admit that I was a bit disappointed that the movie lacks such personality. The film does have the unique access to a DiCaprio that is not on the set of a fictional project or in an awards ceremony tux, but he adds nothing aside from his name and face.

Correctly identifying the most important issue of our time, DiCaprio uses his authority and charisma to travel the world and highlight men impact on our planet. Indeed, he travels the globe examining our fossil-fuel addiction. Where the film succeeds the most is by focusing on the ground-level victims of climate change, such as the polar bears of the Arctic for instance. Of course, the documentary is enforcing the 2015 Paris agreement, in order to develop the wind and solar power.

So many climate documentaries have passed through cinemas and aired on TV, it's impossible to believe that lack of information is the obstacle to change in public policy. This documentary seems important to me as a shift in public opinion has to be achieved to change the political classes opinion. Finally, Before the Flood foes have one marvellous scene that its contemporaries won't have. Former Astronaut Dr. Piers Sellers sits down with DiCaprio in a dark room that is illuminated by a graphic of planet Earth and talks about how his experience in Space helped him understand the massiveness and beauty of the world. He highlights that if we can all see our presence in the world on a much larger scale than what is in front of us, we might be able to change our way of life before it is too late.

Overall, Before the Flood is a serious, substantial and very important piece of work.

Greetings again from the darkness. Ten years ago Al Gore became a climate-change icon thanks to the Oscar-winning documentary An Convenient Truth (from director Davis Guggenheim). With this updated warning, the climate change crown is passed to Leonardo DiCaprio, and rather than just speak to the topic, he takes us on a worldwide journey to show us the effects.

The film is bookended by DiCaprio's speech to the UN general assembly after he was named UN Messenger of Peace on Climate Change. It's a reminder that the mega movie star has long been an environmental activist … and yes, before you scoff, he does acknowledge that his carbon footprint is probably larger than ours (an obvious understatement – unless you also travel by yacht and private jets, and own multiple mansions).

DiCaprio's personal story about Bosch's "The Garden of Earthly Delights" hanging above his crib (seriously, how many parents think this is acceptable artwork for a toddler?) acts as a visual to his message that we are on the path of virtual destruction to the earth that we now know.

The power of celebrity in on full display as DiCaprio scores interviews with such luminaries as UN Secretary General Ban Ki-moon, President Obama, Elon Musk, John Kerry, and even Pope Francis. There is also a clip of his long-ago interview with then President Clinton (Bill, not Hillary). However, it's not the talking heads that have the most impact here. Rather, it's the first-hand look at the Canadian Arctic, the disappearing glaciers of Greenland, the sunny day street flooding in Miami, the destruction of Indonesian Rain Forest to capitalize on the palm oil market, and the eroding coral reefs. The film plays like a Tim Burton Travel Channel series … each stop more nightmarish than the previous.

His passion is obvious, though his knowledge less so. DiCaprio understands the power his celebrity brings, and he joins with director Fisher Stevens (known mostly for his acting, but also an Oscar winning director for The Cove, 2009) in this attempt to bring the urgent message to the masses. As they state, we are beyond simply changing lightbulbs, and the key is a shift from fossil fuels to renewable energy … a shift that China (not the U.S.) has taken seriously.

With generic solutions like "consume less" and "vote better", the film mostly avoids controversy … though it does acknowledge the slick and well-funded 'campaign of denial' by those who profit mightily from a fossil-fuel dependent world. We see an impressive map/video screen tracking ocean currents, temperatures, etc. and there is a chart comparing electricity usage by U.S. citizens vs other countries (we are energy hogs, in case you weren't sure). The ending message hasn't changed much in the past 10 years … "It is all up to us".

I am glad that this documentary was made, even though I felt it was talking to someone other than me. The movie is focused on America (even though what it preaches is relevant all over the world), and much of the information is not really ground breaking if you are already concerned about the environment. I am not complaining about this, as that is probably the best target audience to try to reach for a documentary like this. There's no reason to make more documentaries preaching to the choir.

The documentary itself is mostly well made. Leonardo travels from one place to the other, and talks with some big names. Some of it feels kind of irrelevant, and the best parts is when Leonardo talks with people who are not that famous, especially the one subject that shows her frustration. Some of the places he travels are interesting to see, though it's mostly quick visits, and at times they feel more like backdrops than important set pieces. Despite the documentary jumping from one theme to the next, it holds together quite well, and Leonardo's journey functions well as a mean to take the viewer through all the information.

Personally I would have liked a documentary that was a bit more science heavy, maybe like a combination of the nature trips that Leonardo goes on here, and the presentation from Al Gore's film. But I can understand why they went in the direction they went here, and I hope it resonates with a lot of people that have not thought much about this.

Being the objective of this documentary to raise awareness and support DiCaprio's activity as a "UN messenger of peace" and environmental activist, I believe it really achieved its goal as it is truly a breathtaking, eye-opening film which urges the viewer to strive for a change.

Throughout the documentary we are presented with shocking information, images and educated people's opinion on the matter (like world leaders and scientists) which adds credibility to it. Leonardo DiCaprio and his team do not spare criticism on some of the biggest countries (like the US) policies and on the fossil fuel industry.

Leo's charisma and ability to persuade and entertain the public allied to his drive as an environmental activist just leaves you glued to your seat thinking what can you do to make a change. I believe this really is the kind of information that should be more out there and DiCaprio's celebrity-status, as well as all the other people interviewed, is great for visibility.

If anything, I just wish this was a mini-series to know even more about this issue the world is facing, which might just be the biggest one it ever did...

I give such an evaluation of the film because of its potency to make people humble and make them think more than usual. Notwithstanding the possibility of pure propaganda in the service of one's interests, any film of this kind can not be deprived of valor because it is showing how important it is protecting nature - our home, and shows us that with our everyday choices and decisions we influence globally to everyone and everything else.

Thanks to movies like this one the stereotypes are becoming more clear. It shows how they are exposed and visible especially for the life in the cities. Instead of paving new paths people prefer to go with the flow. Without improving the consequences of their actions, people do not even think about them. They hardly link the environment and the interests of large corporations.

For the first time the viewer is provided with new data and is shown of the precise consequences that will occur in the earliest stages of global warming. Which, by the way, has already begun. Let's hope that the colonization of Mars will lead to a second leap in human development since the discovery of America and will point the right direction for it.

Perhaps one of the most essential films of DiCaprio. Last but not least, seeing Leonardo playing himself is also an interesting moment of the film.

National Geographic comes as a guarantee of the quality of the film strip which is presenting lots of beautiful natural sceneries.
