UPDATED: The Academy of Motion Picture Arts & Sciences apologized on Tuesday for the Asian jokes on the Feb. 28 Oscar telecast, after receiving a protest letter signed by 25 AMPAS members, including Ang Lee.

An Academy spokesperson issued the statement, “The Academy appreciates the concerns stated, and regrets that any aspect of the Oscar telecast was offensive. We are committed to doing our best to ensure that material in future shows be more culturally sensitive.”

The letter asked for “concrete steps” to ensure that future Oscarcasts will avoid the “tone-deaf approach” to Asians that was exhibited last month. The protest was delivered in advance of today’s board meeting, where the Oscar show and issues of diversity are undoubtedly on the agenda. The missive was sent to the board, AMPAS president Cheryl Boone Isaacs, CEO Dawn Hudson, and ceremony producers Reginald Hudlin and David Hill.

The letter said, “We are writing as Academy members of Asian descent to express our complete surprise and disappointment with the targeting of Asians at the 88th Oscars telecast and its perpetuation of racist stereotypes. In light of criticism over #OscarsSoWhite, we were hopeful that the telecast would provide the Academy a way forward and the chance to present a spectacular example of inclusion and diversity. Instead, the Oscars show was marred by a tone-deaf approach to its portrayal of Asians.

“We’d like to know how such tasteless and offensive skits could have happened and what process you have in place to preclude such unconscious or outright bias and racism toward any group in future Oscars telecasts. We look forward to hearing from you about this matter and about the concrete steps to ensure that all people are portrayed with dignity and respect.

“We are proud that the Oscars reach several hundred million people around the world of whom 60% are Asians and potential moviegoers.”

In addition to Lee, other Oscar winners on the list include Chris Tashima (shorts and feature animation) and four members of the documentary branch: Ruby Yang, Steven Okazaki, Jessica Yu and Freida Lee Mock. Aside from Mock, two other former governors signed, Don Hall (sound branch) and Arthur Dong (documentaries). Another three signers were Oscar nominees: Christine Choy, Renee Tajima-Pena and Rithy Panh, again all docu-branch members.

Other signers were Yung Chang, documentary; Maysie Hoy and William Hoy, editors; Marcus Hu and Teddy Zee, executives; Janet Yang, producers; David Magdael and Laura Kim, PR; and six members of the actors branch: Nancy Kwan, Peter Kwong, Jodi Long, France Nuyen, Sandra Oh and George Takei.

According to the International Energy Agency, Asians represent 4.3 billion, or 60% of the population. However, they are estimated to represent less than 1% of the Academy.

Sources close to the show told Variety that Chris Rock made decisions about his material (including a series of jokes about Asian children), while Sacha Baron Cohen’s crack was apparently ad-libbed. However, at a time of heightened sensitivity with racial matters, many viewers were shocked that old Asian stereotypes were trotted out for a laugh.
