A woman who once based a work around Star Wars character Jabba the Hutt is one of the four artists shortlisted for this year's £25,000 Turner Prize.
Performance artist Lali "Spartacus" Chetwynd joins Luke Fowler, Paul Noble and Elizabeth Price on the shortlist.
The prestigious prize is awarded to a British artist, under the age of 50, considered to have put on the best exhibition of the last 12 months.
The winning artist will be announced at Tate Britain in London on 3 December.
Sculptor Martin Boyce, whose works include artificial trees and a leaning litter bin, won in 2011.
This year's judges include Andrew Hunt of the Focal Point Gallery in Southend-on-Sea, Heike Munder from the Migros Museum fur Gegenwartskunst in Zurich, and Michael Stanley of Modern Art Oxford.
Mark Sladen from Denmark's Kunsthal Charlottenborg will also sit on the panel alongside Tate Britain director Penelope Curtis, chair of the jury.
Ms Curtis told the BBC she did not think this year's shortlist was "overly challenging".
"It doesn't look like it's setting out to be controversial, I think there's a nice variety," she said.
"I believe that people will see that there's something serious going on here and that these artists have been working for years on very serious projects."
Previous recipients of the prize, first awarded in 1984, include Antony Gormley, Damien Hirst, Steve McQueen and Grayson Perry.
Perry told the BBC Paul Noble would be his pick of this year's nominees.
"He has been a long-time slogger at the coal face of culture and he deserves to be on the shortlist," he said.
The artist, who won the Turner in 2003 for a series of vases depicting subjects like death and child abuse, said the prize was "very relevant still".
"It's still a good calling card," he said. "It's awarded by your peers, so it's important".
However Tracey Emin, who was nominated in 1999, warned the prize was "a bit of a gauntlet".
"It's a lot of hard work being nominated for the Turner Prize and I'd advise anybody who gets nominated for it to think seriously whether you accept it," she said.
Work by the shortlisted artists will be shown in an exhibition at Tate Britain opening on 2 October.
ABOUT THE ARTISTS
Born in 1973, Spartacus Chetwynd made her name by staging recreations of such cultural landmarks as Michael Jackson's Thriller video and F Scott Fitzgerald's The Great Gatsby.
Her work, which has been seen at the Saatchi Gallery, the Migros Museum and Tate Britain, has a home-made aesthetic and often involves an element of audience participation.
The 38-year-old says she "lives and works in a nudist colony in south London" and changed her name from Lali on her 33rd birthday "to remind people they have a choice in life".
Chetwynd is shortlisted for her solo exhibition at Sadie Coles HQ in London.
Born in 1978 in Glasgow, Luke Fowler creates cinematic collages that have often been linked to the British Free Cinema movement of the 1950s.
He was the first winner of the Derek Jarman Award for artist film-makers and had a retrospective at the Serpentine Gallery in London in 2009.
Fowler is shortlisted for his solo exhibition at Inverleith House in Edinburgh, which showcased his new film exploring the life and work of Scottish psychiatrist RD Laing.
Born in 1963, Paul Noble is a painter, draughtsman and installation artist who explores society through drawings of a fictional town called Nobson Newtown.
His drawings depict a dysfunctional dystopian landscape that has seen him compared to the legendary William Hogarth and US cartoonist Robert Crumb.
Noble is shortlisted for his solo exhibition at Gagosian Gallery in London, which brought together his darkly satirical and painstakingly detailed drawings.
Born in Bradford in 1966, Elizabeth Price creates video installations that incorporate moving images, text and music.
According to the Baltic in Gateshead, where her work is currently on show, "she draws upon historical film, photographic archives and collections of artefacts to generate fantasy episodes".
It is for her current exhibition Here, which comprises a trilogy of video installations, that she has been shortlisted.
The nominated artists who do not win the main prize will each receive £5,000.
