Try this mathematical film test, it is astonishing. The test will predict which one of the 15 films listed in the spoiler is your favourite. No idea how it works but 'Airplane' was correctly predicted for me.
Don't cheat by looking at the list first, do the maths then see if it's right.
Here goes...
Pick a number from 1-9.
Multiply by 3.
Add 3.
Multiply by 3 again.
Now add the two resulting digits together to find your predicted favourite film from the list in the spoiler.
I tried it on Mrs M too, it correctly gave her 'Grease'.
