I don't know if any of you follow the soap opera "The Young and the Restless", but there was a character by the name of Colleen who had never been outside of the USA. The character had been recast a few times, sometimes with success, sometimes not.

The last recast was a complete disaster! An Australian girl by the name of Tammin Sursok got the role. With the exception of a local Australian TV show, she had little experience. To cast an Aussie with little acting ability into the role of an American girl was definitely a poor choice. But it was part of her music contract with Sony (get her established into the US market for acting).

She tried to lose her Aussie accent in her scenes, but failed miserably. Eventually the writers/producers just gave up and let her do her own thing hoping the viewers wouldn't notice.  A misplaced Aussie accent on an American character that's never been to Australis is not easily ignored. In addition to that, her acting was terrible. It didn't matter what scene she was in, it looked like she was constantly grinning: Happy, sad, terrified, angry, crying.... didn't matter...grin, grin, grin!

The character was a well loved one for years. But when this girl took over the role, many stopped caring and by the time the character was killed off, no one cared at all. Many of us were relieved to just have the actress gone from the screen.  LOL
