A development deal was secured following Zemeckis' success directing Romancing the Stone (1984). Fox was the first choice to portray Marty, but he was unavailable; Eric Stoltz was cast instead.

This included re-filming scenes already shot with Stoltz and adding $4million to the budget. Back to the Future was filmed in and around California and on sets at Universal Studios. Filming concluded the following April. Replacing Stoltz delayed production and the film's release date but, following highly successful test screenings,
