On the other hand Mel Gibson was Aussie and became American. He's not claimed anymore.
According to Wikipedia, Mel Gibson was born in the US to American parents and moved to Australia when he was 12. Somehow I remembered that factoid when I read your comment :)
Thanks. I didn't fill in that detail. I thought only his mother was American, and I should always check my facts before I post anything here. So in, and then out, but oddly, out in a similar way that Rupert Murdoch is out.
