The Frankenstein Theory (2013)

From the makers of The Last Exorcism comes a boldly original vision of horror. What if the most chilling novel of all time was actually based on a true account of a horrific experiment gone awry? When he is suspended from his university job for his outlandish ideas, Professor John Venkenheim leads a documentary film crew to the rim of the Arctic Circle in a desperate effort to vindicate his academic reputation. His theory: Mary Shelley's ghastly story, "Frankenstein," is, in fact, a work of non-fiction disguised as fantasy. In the vast, frozen wilderness, Venkenheim and his team search for the legendary monster, a creature mired in mystery and drenched in blood. What they find is an unspeakable truth more terrifying than any fiction...a nightmare from which there is no waking.

Unfortunately the movie The Frankenstein Theory is not yet available on HBO Max.
