Yesterday was "Back to the Future Day", and to commemorate the event, Universal re-released the trilogy in 1,815 theaters.  The film grossed $4.8 million so far, and will continue to be shown through the weekend. 

The re-release gave a new generation the chance to experience the now classic film franchise on the big screen for the first time.  The event was widely celebrated, and even Pepsi and USA Today got in on the fun, releasing items shown in the film.  

The franchise has generated over $416 million with its three films: 1985's Back to the Future, 1989's Back to the Future Part II and 1990's Back to the Future Part III.
