Alan Cumming has spoken out after a racial slur was shouted during February’s British Academy Film Awards ceremony, calling the event a “trauma triggering s***show.” Cumming, who hosted the February 22 awards ceremony, apologized again on Instagram on Tuesday, expressing regret for the incident’s impact.

He apologized for “all the pain Black people have felt at hearing that word echoed round the world” and for the backlash that followed, citing the world’s “lack of understanding and tolerance” about the neurological disorder.

John Davidson, a Tourette syndrome activist, used the N-word during the ceremony, prompting widespread criticism. The BAFTAs were pre-recorded, but the slur was broadcast uncensored.

Cumming also appeared to criticise the awards body and broadcaster. “We were all let down by decisions made to both broadcast slurs and censor free speech,” he wrote, adding that “all trauma must be recognised and honoured.”
