Actress Rachel McAdams learned a valuable lesson when working with Russell Crowe - he taught her to appreciate rugby.
The Gladiator star owns professional rugby league team the South Sydney Rabbitohs in Australia, and introduced MCAdams to his beloved sport while they co-starred in new movie State of Play.
And MCAdams admits Crowe did his best to convert the whole crew to supporting his team - even inviting them all to his home to watch a Rabbitohs game on television.
She says, "He was on set that day saying to all of us: 'You have to come and watch the game. We're going to have meat pies.'
"Russell is obviously a big supporter of his team and rugby league in general. He gave us all shirts, hats and scarves. I even got a (Rabbitohs) Christmas ornament.
"I wasn't familiar with rugby league beforehand and I don't profess to be an expert now. But everything I do know about rugby league, I know from Russell Crowe."
