Dear Phoebe; 'STAY OUT OF HOLLYWOOD!'
I don't know WHAT it is, but ANY Actor/Actress who goes to an AMERICAN TV/Movie PRODUCTION COMPANY is, FOREVER, CHANGED and NOT ALWAYS (necessarily) for the better!
I could go on, and list all of the Actors/Actresses who have had their lives IRREVOCABLY RUINED, because of places like Hollywood, New York (Broadway), or Las Vegas to name but a few but, unfortunately, I wouldn't know where to start (there are TOO MANY!)
So, I'll just give you a little Big Brother Advice: Stay True, to yourself; Remember your Roots; and, Avoid Becoming the Spotlight, of ANY "Suspicious" People in other words:
If it looks TOO GOOD TO BE TRUE, then it SHOULD BE CONSIDERED (without a doubt) "TOO GOOD TO BE TRUE!"
(This message is meant, with the SINCEREST ADORATION, for Ms. Tonkin, and shouldn't be, otherwise, inferred!)
The 21st Century is when everything changes, and you've got to be ready!
