Actress Radhika Apte is done with shooting the upcoming thriller and horror film "Phobia".

"Night shoot.. Last shoot day for 'Phobia'," Radhika tweeted.

As the title suggests, the film revolves around some kind of a phobia -- the fear of something.

Radhika was meeting doctors and patients, apart from reading extensively, about the subject to gather as much information as possible for the role.

She was also in close contact with psychiatrists to understand the mental aspect, and neurosurgeons for the biological aspect so that she understands better how a person reacts to a particular phobia. The actress has also been meeting patients and observing them to understand their behavioural patterns.
