Again, movies made for IMAX theaters are arriving on home video from Shout! Factory, this week with Flight of the Butterflies and Rocky Mountain Express.
The former is an absorbing saga which shows how a researcher and his wife traced the mysterious annual migratory patterns of millions of Monarch butterflies over the course of decades — and finally found their secret winter home on a Mexican mountaintop.
That story is told with a mix of wondrous documentary footage of the colorful insects and well-played re-enactments of the researchers, who also included a collaborating Indiana Jones-style young couple roaming Mexico on a motorbike to find the missing Monarchs.
