Nature film to be filmed along Mississippi River
Another movie is being filmed in Wisconsin, but this one doesn't have stars like Johnny Depp.
Wildlife filmmaker Alastair MacEwen is capturing the annual hatching of mayflies in southwest Wisconsin.
This is the time when tens of millions of mayflies expose their larvae.
And MacEwen and his camera assistant Skip Hobbie are filming the activity for a National Geographic feature on their migration in the Upper Mississippi River.
