Producers of the hit HBO fantasy series "Game of Thrones" are facing some pretty big problems after a  pivotal nude scene involving Lena Headey's Cersei Lannister was banned from filming in Croatia.

"Game of Thrones" is currently shooting in Dubrovnik, Croatia. Producers have already secured permission and all the necessary permits to film every scene they need, except for one particular sequence where Cersei is forced to take a Penance Walk, completely naked, across King's Landing.

The scene was set to be shot on Stradun street, between Dubrovnik cathedral and the Sponza Palace in the Croatian capital, according to Independent, where the church has a lot of power and strict rules against public displays of sexuality.

But a source told TMZ that the local film commission refused to give producers a permit to shoot the specific scene in accordance to the order of the church - the Church of St. Nicholas.

And while producers have not yet reached a solution to the problem, some entertainment news sites provided a number of options that the showrunners might take.

David Benioff and D.B. Weiss might decide to give Headey "small, flesh-colored underwear and shoot from angles that would obscure the actual nudity," Cinema Blend reported. They might also find another location, where they could shot the scene unedited, but this option would definitely cost the production more money.

They might also opt to use some "more gorgeous, very expensive CGI," according to Gawker. Worst-case scenario: they might choose to completely cut the scene from the new season.

If the iconic scene from George R.R. Martin's fifth novel "A Dance With Dragons" will not be part of the upcoming season, it is believed that it will be included in later seasons because it is highly significant to the series' overall storyline.

Filming for the fifth season of "Game of Thrones" is ongoing, with majority of scenes having already been completed in Northern Ireland, AAP reported.

"Game of Thrones" Season 5 premieres on HBO in April 2015. The last two seasons of the shows, on the other hand, will only be filmed once Martin has written his final two novels, "The Winds Of Winter" and "A Dream Of Spring."
