Sons Of Anarchy producers have angered officials at America's Parents Television Council by screening a graphic sex montage featuring star Charlie Hunnam.

The episode of the motorcycle drama, which aired on the Fx network last Tuesday (11Nov14), opened with a three-minute long scene featuring a number of characters engaging in sexual acts as they attempt to deal with the death of another character.

Upset with the content of the episode, which featured shots of Hunnam's bare bottom, Ptc president Tim Winter released a statement slamming network bosses at Fx for allowing explicit content to be aired on cable.

It reads: "It's official: In order to watch cable news, Espn, Disney or the History Channel, every family in America must now also pay for pornography on Fx.

"Last week's episode of Sons of Anarchy opened with the most sexually explicit content we've ever seen on basic cable, content normally found on premium subscription networks like HBO or Showtime... If Fx wants to be like Hbo and air this kind of explicit content, then they should become a premium network.

"Families should not be forced to underwrite pornography. Cable Choice is a solution whose time has come, and there could hardly be a better example of it than this."

Both series creator Kurt Sutter and network representatives have made no immediate comment.

Sons of Anarchy, which airs at 10pm and features a 'mature' rating disclaimer before the show and after every commercial break, has upset the Ptc in the past - last year (13) bosses were appalled by the depiction of a school shooting in its season six premiere.

Winter then urged viewers upset with the violent plotline to contact their local politicians and call for them to back a bill that would allow consumers to purchase customisable cable options, instead of receiving a package which would automatically include the Fx channel.

Sutter came to the defence of his series, saying, "I would imagine these are not evil people, but they are... just not very intuitive or intelligent individuals."
