On March 19, 2021 a volcano erupted in Iceland that captured the imagination of people from all over the world. It also changed the lives of April and Martin, independent filmmakers living in an apartment in New York City. Like many of us they were coming out of a long winter dealing with covid - 19. This eruption spawned an idea for their next film. They decided to travel to Iceland to film the eruption and gather stories from the remarkable people who live with the joys and challenges of volcanic eruptions right in their own neighborhoods! Find out how April and Martin created this powerful film.

You can find out how to watch the film at fireandiceland.com. I would love to hear your reactions to the film. You can leave a comment on our website or email me at [email protected].
