I love Celebrity Mastermind. Far more so than on the civilians' version, it allows the contestants' specialist subjects to be fantastically specific in order to ensure them a certain measure of first-round smarts. (If I was a famous contestant, I might choose 'The First 5 Minutes Of The Sound Of Music' or 'The lyrics to Elton John's Song For Guy').
In any case, you wouldn't want recent contestant Ian Lavender wasting unnecessary time revising the life and career of Buster Keaton when he should be hard at work researching his role in Morph And Me – the Tony Hart biopic. (There are better titles out there. I am too tired to think of them.)
Or perhaps he's busy prepping to play Merrill Osmond in What's The Story Mormon Glory: The History Of The Osmond Family.
I did say I was tired.
