Patrick Wilson and Rose Byrne on for Insidious 2
Insidious is a horror fantasy film about a family that looks to prevent evil spirits from trapping their comatose child in a realm called The Further.
Patrick Wilson and Rose Byrne have signed up to star in 'Insidious Chapter 2'.
The pair - who played parents trying to stop their son from becoming possessed in the first installment of the horror film - have negotiated their return to the franchise, with director James Wan also coming back.
The first film was one of the most profitable of 2011 thanks to it making $97 million worldwide on a $1.5 million budget.
Original screenwriter Leigh Wannell has written the script for the movie, while Jason Blum will also resume producing duties.
Although an exact date of filming is not known, it is planned for release on August 30, 2013.
It is also unknown how the story will progress from the first film.
Patrick Wilson was last seen in 'Alien' prequel 'Prometheus' and is also lined up for a starring role in 'The Conjuring', while Rose - who had a spectacular 2011 with 'X-Men: First Class' and 'Bridesmaids' - has recently completed roles in 'I Give It A Year' and 'The Internship'.
