No one believes that Trevor Anderson (Brendan Fraser) is on to something. The science professor's unconventional hypotheses have put him on the fringe of the academic community. But during an expedition to Iceland, Trevor and his teenage nephew, Sean (Josh Hutcherson), accompanied by their beautiful local guide, Hanna (Anita Briem), make a breakthrough discovery that launches them on a thrilling adventure into the unknown. As their journey takes them deep beneath the Earth�s surface, they travel through never-before-seen worlds that bring them face to face with surreal and unimaginable creatures, stretching the bounds of the visionary scientist�s own imagination. Academy Award-winning visual effects artist Eric Brevig makes his feature directorial debut with this adaptation of the classic Jules Verne fantasy.
