Kiefer's dad plays the diva

Kiefer Sutherland’s dad Donald is reportedly driving the producers of a bank commercial mental with his diva-like demands.

Sutherland senior is shooting the ad in London.

The veteran actor will only drink a specific brand of water that must be served to him at exactly the right temperature.

But his most over-the-top demand? He told a horrified assistant to trim his nose hairs! Needless to say, the request was refused pronto.
