What is the only rule when you have had a great one-night stand? That’s right – don’t go back. It won’t be the same. The planets will not align again. It is over. Move on.
The same principle – as actors, commissioners and agents ought to know – applies to TV hits. If you have been in The Wire, don’t do another cop show. If you struck gold in The Sopranos, don’t take any of the mobster roles you are offered thereafter. The chance of lightning striking twice is infinitesimal. The chance of reminding yourself and viewers how good you had it is correspondingly high.
