Howard: 'Crowe's tantrums great for his acting'

Oscar-winning film-maker Ron Howard is happy to tolerate Russell Crowe's temper tantrums, because they usually precede his best performances.

The former Happy Days star has teamed up with Crowe twice - on 2001's A Beautiful Mind and this year's Cinderella Man - and he has found approaching the Australian actor with simple logic is the best way to transform his anger into mesmerising acting.
