Freddie Fox has dismissed Benedict Cumberbatch's complaint that he has been the victim of "posh bashing".

Sherlock star Benedict, 38, raised eyebrows when he said that he was considering moving to the US because he was fed up with being " castigated" for his p ublic school background.

But Freddie, the 25-year-old member of the famous Fox acting dynasty, rubbished the TV turned Hollywood star's remarks.

"A load of b******s. I mean, Ben's doing alright, isn't he?," the privately educated son of stage and screen actor Edward Fox told Radio Times magazine.

"It's not like too many people are hating him in Hollywood!"

Freddie stars in new movie The Riot Club, about a fictional, exclusive Oxford undergraduate dining society which has fuelled comparisons with the Bullingdon Club, associated with Prime Minister David Cameron, Chancellor George Osborne and London Mayor Boris Johnson.

Freddie said that he was "sort of over" concerns that people would think "I'm a posh git" if "I keep doing films like The Riot Club ".

But he added: "I do want people to think of me as an actor, not just a posh actor who does posh parts."

His comments came as The Walking Dead star David Morrissey voiced concern that the acting business was becoming the preserve of the wealthy.

"There's an economic exclusion of working-class people happening now. I got lucky, but if I was starting out now, it would be a lot harder, because my parents could never have supported me through that 'Is it going to happen?' period", he said.

"I was able to go to drama school with a grant. I was able to do stuff at the Everyman and work there at the same time.

"Too often now, people come into the profession subsidised by their parents and they're not being paid."

David, who stars in new BBC One drama The Driver, told Radio Times: "It worries me that in the arts, which is essentially a very rich community, we're not offering more support. Television is doing very well for itself, but the trickledown effect isn't working."

Call The Midwife star Stephen McGann and veteran actress Julie Walters had previously complained about the dearth of young actors from poorer backgrounds.

"The way things are now, there aren't going to be any working class actors," Julie said. ''I look at almost all the up-and-coming names and they're from the posh schools."

Old Etonians such as Dominic West and Damian Lewis have shot to the top of the acting world, with the likes of Tom Hiddleston and Eddie Redmayne are also enjoying success.

The Fifth Estate star Benedict previously said that he was sick of being attacked over his privileged background.

''I wasn't born into land or titles, or new money, or an oil rig,'' he said. ''It's just so predictable ... so domestic, and so dumb... It makes me think I want to go to America.''
