Paranormal Activity: The Marked Ones Hidden Message Hunt

Spot the hidden clue in this Paranormal Activity: The Marked Ones clip and you could win a Samsung home entertainment system

There's something extra in the Paranormal Activity: The Marked Ones clip above. A hidden word has been added to the footage, and if you've spotted it, you can visit the movie's official Facebook page to find out where the other hidden messages can be found. Once you've got them all (the competition opens at midday on Tuesday 6 May), you should be able to form a phrase from the film.

Once you've worked out the phrase, you can direct message your answer to the Facebook page to win a Samsung home entertainment system and a copy of Paranormal Activity: The Marked Ones on Blu-ray. Ten runners-up will win a copy of the film on Blu-ray. You need to hurry, however – all entries must be received by midnight (UK) on Monday 12 May 2014.

Paranormal Activity: The Marked Ones is out on Blu-ray and DVD on Monday 12 May.
