Q: Rex Harrison won a Tony award for playing which King in Anne of a thousand days?

A: King of Siam!

[Cloverjo]

As I always say on this type of question, better to guess something than to pass. 
I get more annoyed by passes than wrong guesses. 

[ToraToraTora]

yes but why would you not guess the most famous king in history? ...and you'd be correct!

[1ozzy]

Would the most famous king be the one that decapitated numerous wives?

Now that's a claim to fame!!

[davebro3]

numerous? = 2

The contestant was obviously thinking of Anna and the King of Siam.  

[1ozzy]

Well,  it's more than one,,

[naomi24]

You might know the story of Anna and the King of Siam better as the musical 'The King and I', TTT.  I don't think the answer given was a terrible blunder.

[10ClarionSt]

I'm with TTT on this. Hilarious! 😃

[Canary42]

Surely the most famous king in history is the King of Heaven 😀 😀 😀 😀

I don't usually chuck in my tuppence worth ... but must admit that was funny.
