Kiwi filmmaker Dylan Reeve came under fire this afternoon from a man at the centre of his Tickled documentary, who burst into a US screening of the film and accused Mr Reeve of lying.
The man, understood to be David D'Amato, brought to a halt a question and answer session on the professional tickling documentary at the Nuart Theatre in Los Angeles at 4pm New Zealand time.
He claimed Mr Reeve and the documentary's co-creator David Farrier, used recorded information from a subject that they agreed not to.
The man was booed by fans in the awkward standoff which was broadcast live on Facebook, prompting a flurry of postings on social media.
