Some people dream about becoming engineers, Luckily, the new IMAX film Dream Big shows how engineering can improve people’s lives. It teaches viewers how engineers use high-tech to help the world. The film hits IMAX theaters nationwide on February 17 to celebrate Engineers Week.

The film, taking place in locations like China, Dubai and Africa, tells the stories of engineers who try to come up with creative ideas to save energy and help people.

Dream Big was directed by Greg MacGillivray who has 38 films under his belt, including some of the most successful films ever shown in IMAX theaters.

How did MacGillivray get into the moviemaking business? “I grew up at the beach. My first movies were about surfing and the ocean. As time went on, I saw the changes in the ocean including polluting and overfishing. So I started making films about conservation of nature.” He told TFK. Now, his films cover a variety of topics, from the natural world to human creation.

One of the engineers in Dream Big is Angelica Hernandez. In high school, she was on a team that best MIT, a university, in an underwater robotics competition. Today, the engineering work she does focuses on helping people use less energy and save money and resources. “I work with companies to promote energy efficiency with their commercial customers, so it’s really trying to push forward all the measures that customers and high-energy users can apply, she explains.

Engineering is such a good job-you make good money, travel around the world, solve amazing problems and help people.” She says.

The mission of Dream Big is to show people the good that engineers can do to the world. “That was the impulse of making this movie”, MacGillivray explains, “We want to explain engineering in a way that will get the kids very excited about it.” “Whoever and wherever you are, you can become an engineer,” he adds, “All you need is the creative spirit.”
