It has been quite a week for science-fiction philanthropists.

Star Wars filmmaker George Lucas finally opened his Museum of Narrative Art in Los Angeles and now George Takei, best known for playing Sulu in the original Star Trek, has announced he will leave his and his husband's entire estate to the city's Japanese American National Museum.

Takei said the future gift, valued at more than $21 million, would "ensure that for generations to come, the museum will remain a vital and active place for our community to come together to learn, reflect, and be inspired to continue the fight for a more just future".

The actor, born in Los Angeles to Japanese-American parents, is a founding trustee of the museum which is set to reopen next year after a multi-million-dollar refurbishment.

He previously gave the museum his personal archive including a sculpture made by his father while the family were held along with thousands of other Japanese-Americans in an internment camp during World War II - an experience he has written and spoken about extensively in recent years.

It is fair to say Jonathan Abbott's appointment as director and CEO of the Los Angeles Museum of Contemporary Art (MOCA) has come out of left field.

Abbott, who previously spent 15 years running Boston public broadcaster GBH, is its sixth director in 18 years.

He replaces interim director Ann Goldstein who stepped in when Johanna Burton left for the Institute of Contemporary Art in Philadelphia. Burton in turn replaced Klaus Biesenbach who lasted three years before leaving for Berlin's Neue Nationalgalerie.

The constant churn at the top along with staff layoffs has damaged the museum's image though recent shows, particularly Monuments which featured new work made from decommissoned Confederate symbols, have been praised by critics.

Abbott, who helped GBH reach new audiences and raise around $215 million, told the New York Times he was ready to lead the Californian institution but admitted the art world's dress code and party calendar would take some getting used to.

He said: "We’re a little bit more makeshift in public media."

The asking price for the Beverley Hills home of publishers Benedikt and Lauren Taschen which was previously part of Charlie Chaplin's estate.

Hieronymous Bosch, Goya, Superman and cult musician Frank Zappa all feature in the well-named Bizarre exhibition opening at Berlin's Art Library.

The show, which includes works such as Claude Gillot's surreal human snail, traces the history of the word from its first appearance in Dante's Inferno and ends with a two-sided painting by Bosch.

Bizarre: The History of the Strangest Word in the World is curated by Moritz Wullen and runs from November 27 to March 29.
