Warner Brothers to develop UK film base near Watford

Europe's biggest film studio complex is to be developed at a site near Watford.

Warner Brothers will invest £100m into Leavesden Studios in Hertfordshire where all the Harry Potter films were shot.

The development, which includes a new area to house props and costumes from Warner films made in the UK, could sustain 1,800 jobs in the area.

Will Gompertz reports.
