The UK's Pinewood Studios has warned film revenue may be reduced this year because of delayed studio productions.

The UK studio has been performing well recently and was further boosted this year by news that it would host the next Bond movie.

Current business includes Chris Weitz' His Dark Materials: The Golden Compass at Shepperton and Tim Burton's Sweeney Todd at Pinewood.

Half-year pre-tax profits rose 39% year-on-year to $5.86m (£2.9m) on revenues of $36.8m (£18.3m), down a little from from $37.6 (£18.7m) in 2006. More than half of turnover comes from film with the rest from television.

But there are strong concerns about delayed productions and further disruption caused by possible strike action around next year's Hollywood contract negotiations with actors and screenwriters.

The company intends to look to build its television business to increase stability.

'Pinewood Shepperton is making steady progress on ourstrategic developments for the future of the business as we movetowards more diversified and higher quality revenue streams,'Chief Executive Ivan Dunleavy said in a statement.
