Shows including The Big Bang Theory and Modern Family have been taken off-air in Spain amid a strike by voiceover actors.

The artists who provide Spanish language lines for U.S. shows have walked out as part of a union protest against pay cuts, and studios have been left with a backlog of new episodes which are undubbed.

Shows including The Big Bang Theory, Modern Family and Grey's Anatomy have been taken off-air, with network bosses replacing new episodes with re-runs.

The launch of the upcoming fourth series of Game of Thrones next month (Apr14) also looks set to be delayed unless the dispute is resolved, according to Britain's The Guardian newspaper.
