Where is Too Close filmed? Filming locations of ITV thriller - from Kent to Holloway Prison

Too Close starring Emily Watson is thrilling and chilling ITV audiences in equal measure.

The dram follows dedicated forensic psychiatrist, Emma Robertson, who is assigned to work with Connie Mortensen, a wife and mother accused of a despicable crime.

Set over three episodes the show focuses on the bond and conflict between the duo.

ITV itself describes the drama as story about “a powerful – but dangerous – closeness between two women”.

Where is Too Close filmed?

Too Close was filmed on location in London and Kent.

The bulk of the scenes featuring the two leading actresses were filmed at the now closed Holloway Prison in London.

Emily Watson told The Sun newspaper's Bizarre TV column: "we thrived filming the scenes in the psychiatric unit. Actresses like me and Denise, that’s what we love doing.

“That’s like a really great day at the office. It’s thrilling to do. A real acting workout. We filmed the psychiatric unit scenes at the now-closed Holloway Prison in London.

“It was a really grim place. Now a dead building which has housed so many sad lives. Those scenes are very intense.”

The show also features Sheppey Way and Kingsferry Bridge in Kent.

During filming a local cyclist complained that they were forced to use Sheppey Way to get home during high winds. Crossing Sheppey Way by bicycle is illegal.
