Back To The Future (1985)

In 'Back to the Future', Marty McFly and Doc Brown meet up at Twin Pines Mall to travel back in time to 1955. Later on, after McFly is being chased he accidentally hits one of the two pine trees (nearby). The future has been changed but when he arrives near the end of the movie, it appears that an effort was made to fix this mistake - changing the name from 'Twin Pine' Mall to 'McFly' Mall.
