Film composer to write 15 minutes of additional music for a performance by the Royal Scottish National Orchestra.

Edinburgh International Film Festival (EIFF) and the Royal Scottish National Orchestra (RSNO) are to celebrate the 30th anniversary of EIFF’s UK premiere of time travel classic Back To The Future with a screening this summer.

The Robert Zemeckis film starring Michael J Fox will be screened at Edinburgh’s Festival Theatre on June 27 accompanied by Alan Silvestri’s score performed live by the RSNO.

This presentation will include a newly expanded score by Silvestri with approximately 15 minutes of additional music being prepared by the composer.

The special screening will mark the start of a programme to celebrate EIFF’s heritage and legacy over the past 70 years.

New EIFF artistic director Mark Adams said: “This live event will delight and enthral in equal measure.  As well as being a major event in its own right, this also marks the beginning of a new set of relationships with Scotland’s National Performing Companies, where we are placing film within the context of other artforms.”

The 69th edition of EIFF runs from June 17-28, 2015.
