Glasgow auditions for a part in the new Star Wars film have been postponed as producers battle to find a larger venue for the event.

Casting directors had to turn people away during their first audition in Bristol last weekend after being overwhelmed by the response to their open casting call. It is understood that around 5,000 people turned up over two days.

The Glasgow auditions, which were due to take place at South Block, Wasp Studios, 60-64 Osborne Street on Saturday, November 16 and Sunday, November 17, will now take place on Saturday, November 30 and Sunday, December 1. The venue for the auditions will be announced later this month.

Producers want to find two young actors to fill lead roles in Star Wars: Episode 7. Film-makers are looking for a young, beautiful, smart, athletic woman to play a 'street smart and strong' orphaned teenage girl in the movie. They are also searching for a handsome, smart, athletic youngster to fill the role of a 'smart, capable and courageous' man in his late teens or early 20s.

The sci-fi flick will be directed and co-scripted by JJ Abrams, best known for his work on Lost and the last two Star Trek movies. It is due to begin shooting at Pinewood Studios in Spring 2014 and is scheduled for a 2015 release.

It is rumoured that the film will star Harrison Ford, Mark Hamill and Carrie Fisher, who appeared in the original trilogy.

A statement posted on @UKopencall, which announced the auditions, said: "The open casting call scheduled for this weekend, November 16 and November 17 in Glasgow has been rearranged for the weekend of November 30 - December 1. Due to the overwhelming response at recent sessions the casting team is in the process of searching for a larger venue that can best accommodate projected attendance numbers. We sincerely apologise for any inconvenience.
