George Lucas has said he won't rule out Los Angeles if his ambitious construction project the Lucas Museum of Narrative Arts falls through in Chicago.

The museum is currently set for the shores of Lake Michigan but has been beset by legal issues.

In an interview with the Los Angeles Times, Lucas has said he would consider taking his project west in a bid to see it completed in his lifetime.

"The advantage Los Angeles has is that it's on the USC campus and I don't have to go through all the rigmarole of years and years of trying to get past everything," Lucas told the publication. "That's an advantage because I do want to get it done in my lifetime."

Designed by MAD Architects, the museum is set to feature a futuristic building topped by a "floating" disk, inspired by the work of famous architects Frank Lloyd Wright and Mies van der Rohe.

It will feature three levels of exhibition space displaying some of the treasures Lucas has amassed throughout his glittering career as a filmmaker.

Slated to open in 2018, it will combine narrative art with the evolution of the visual image, focusing on everything from illustration to cinema to the digital arts.
