Actor Eddie Marsan revealed he was inundated with antisemitic abuse after portraying a Jewish anti-fascist.
Mr Marsan, who played taxi driver Soly Malinovsky in TV drama Ridley Road, shared screenshots of Twitter abuse he had received, calling it 'relentless'.
He said: 'All I did was play a Jew, I dread to think what would've happened if I was actually Jewish.'
His character on the programme is a taxi driver who led the 62 Group - Jewish activists who fought neo-Nazism in 1960s Britain.
Mr Marsan, 53, told The Times he hoped publishing the abuse he received - including being accused of 'apartheid loving' - would bring attention to antisemitism.

'I was using my non Jewishness to highlight the fact that this is ridiculous,' he said. 'Sometimes if a Jewish actor or writer or artist highlights it, it is diluted because people kind of expect it.'

One social media user had criticised Mr Marsan for 'gaslighting' fans.
Mr Marsan said that his co-stars such Tracy-Ann Oberman - who was outspoken about claims of antisemitism in the Labour Party under Jeremy Corbyn - had been the subject of 'traumatic' abuse because they are Jewish.
'If you make a film about racists or antisemites and you highlight historical abuse, which also resonates with what's going on now, you're going to p**s off racists,' Mr Marsan said.
