While filming The Lion the Witch and the Wardrobe, Skandar made up a song for checking the gate.  Here it is:

"Check the gate.

Watch yourself;

Check the gate.

Show 'em what you got!"

[repeat five times]

"And Check!"

Skandar is an Atheist.

Anna does not have a MySpace and anyone claiming to be her is a fake.
