The 75-year-old star said love for their job keeps the actors going because they are not financially stable, reported Contactmusic.
"Most actors are not rich, they are very poor indeed. What keeps them going is that they just love the job. I know actors who have had to turn down good roles because they just don't pay enough. It's hard," he said.
"Money is a factor in my life but it's not a major factor. I've never had to worry about it - I learnt very early on to pay my taxes on time and live within my means, which has served me well," he added.
