David Lynch has branded people who watch movies on smartphones and portable computers as ''pathetic''.

The director has lambasted those who enjoy films on the go, insisting movies should only be seen in a dark room with ''great sound''.

Speaking in The New Review magazine - available in this week's Independent on Sunday newspaper - the 67-year-old filmmaker: ''If you have a chance to enter another world ... it's a spiritual, magic experience. If you have the same movie on a little computer screen with bad sound - and this is the way people are seeing films now - it's such a shame. It's a shameful, shameful thing. It's so pathetic.''

Lynch - whose cinematic efforts include 'Dune', 'Mulholland Drive' and 'Inland Empire' - is known for his controversial and surrealist movie style, and for speaking his mind.

He also hinted that he may never make another film, and Lynch blames the profit obsessed movie industry and the death of avant-garde cinema for his ''depressing'' lack of a future movie career.

He said: ''With alternative cinema - any sort of cinema that isn't mainstream - you're fresh out of luck in terms of getting theatre space and having people come to see it.

''Even if I had a big idea, the world is different now. Unfortunately, my ideas are not what you'd call commercial, and money really drives the boat these days.''

David, who is married to actress Emily Stofle, added: ''So I don't know what my future is. I don't have a clue what I'm going to be able to do in the world of cinema.

''And television is way more interesting than cinema now. It seems like the art-house has gone to cable.''
