LOS ANGELES - CTV and the U.S. channel FX has ordered 90 more episodes of the Charlie Sheen sitcom 'Anger Management.'

The unusually large order reflects the original agreement that CTV and FX made for the sitcom, which marked Sheen's return to TV after he was fired from 'Two and a Half Men.'

As part of the deal, FX set a ratings target for eight of the first 10 episodes of "Anger Management." The show reached the threshold, earning an automatic 90-episode order.

FX says "Anger Management" is cable's highest-rated new comedy series this year, averaging 4.5 million viewers in the U.S.

FX Networks executive vice-president Chuck Saftler says he's confident the producers and cast will be able to produce another 90 episodes during the next two years after quickly turning out the first 10.

'Anger Management' is broadcast in Canada on CTV and on FX south of the border.
