4. Clean freak Christian Bale

Christian Bale’s assistant wrote a whole book about the life of a movie star. Harrison Chun remembered how in the long absence of the actor, he had to watch after the whole bunch of opossums living in the backyard. But even this was not so disgusting as to sniff the armpits of Christian, before going on the red carpet. The actor asked to inform, if there was any smell other than a deodorant.
