Veteran film-maker Robert Altman has vowed to carry on making movies well into his 80s, so he can battle the Hollywood trends he believes are killing cinema.

The 80-year-old M*A*S*H director is convinced Hollywood is in demise because of its fixation with massive profits, and the rising popularity of DVDs.

He says, "I'm getting a bit long in the tooth and my parts are wearing out. I can put in a seven but not a 12-hour day.

"But I've got loads of ideas I'm working on at the moment. I'm just apprehensive about the way cinema as a whole is going.

"The business is run by accountants who, as long as the film makes $40 billion (GBP22 billion), don't care if it kills the industry.

"Everything can also be shown so quickly in the home - which means that the people who go to movie theatres are teenagers who just want to get away from home.

"The audience has changed and the content has changed to suit that audience. But even if I'll be an outdated item very shortly, I intend to carry on as long as I can."
