Al Pacino doesn't see the ''point of quitting''.

The 75-year-old actor - who's appeared in some of cinema's most iconic roles, including Michael Corleone in 'The Godfather' films and Tony Montana in 'Scarface' - has revealed he has no intention of quitting the movie-making business, despite his advancing years.

He said: ''I have no desire to quit. Sorry. Why? Why didn't I quit 20 years ago, 40 years ago? What's the point of quitting?''

Pacino revealed he developed his zest for life after a close friend of his died from cancer at the age of just 35.

He told The Guardian newspaper: ''I had a friend who died of cancer at 35. That's young. I was sitting with him a good deal of time and at one point he said to me, 'I want to tell you something I've learned: three months, 30 years.' No difference. That was the insight that he got when he was close to death. And I understand that.''

However, Al is happy to acknowledge that some professions simply don't allow people to carry on forever.

He said: ''A painter can be 100 and paint a group of college kids playing football. It doesn't matter, because he's not playing football. He just grabs a brush and does the strokes. That's the difference (with age). That's really all it is.''
