Here's the trailer for Mike Slee's Flight of the Butterflies in 3D from Yahoo:
Following the year-long annual migration cycle of the butterflies, the award-winning production team filmed hundreds of millions of monarchs in their remote overwintering sanctuaries in Mexico in 2011 and again in 2012 and also along their migratory routes from Canada, across the U.S. and into Mexico. The technology of IMAX immerses you in the astounding migration experience as two generations of the butterflies migrate north and then a Super Generation miraculously finds its way from Canada to a few isolated mountaintops in Mexico in Flight of the Butterflies coming to IMAX screens in 3D on October 1st.
