Super 8 Renamed Darlings?

It seems that Super 8 is going to experience a name change, at least based on the release of the teaser trailer in Brazil. MovieWeb has posted that trailer and if noticed at the end, where it normally says "Super 8", it instead says "Darlings", and no that is not the Spanish translation of the movie. The website tried to verify the name change with Paramount. It isn't known if this is a worldwide, Brazil only or international title change. My guess is Paramount is assuming that most international audiences will not know what a Super 8 camera and film is and chose a name that might be less confusing. Then again a name of "Darlings" for a film with a trailer of a dramatic train derailment and sudden attack is confusing too.
