Trying to recall of a movie I saw around 2005-2007 (movie date might be around this time as well), one of those "group of young people go to a house in the woods, away from the city". But this one consists of the group being contestants of a big brother-like show, where they would be confined at this house, and they were monitored everytime by a cameraman who followed them everywhere.
I remember the house being pretty modern, with sofas and the walls to be red and purple colored. At the beginning one of the guys (I think the show producer) goes to the woods and disappears, being apparently attacked by something. From this part on, everyone gets scared and one by one they are kidnapped, but they could never see what took them. There is a particular scene I remember when they find out the cameraman is gay and the group uses one of the guys to seduce him and distract him while some of them escape/investigate I think.
At the end, there is only one person who walks out of the house alive and well (can't remember if it's a guy or a girl), and he/she discovers in the end it was all a prank by the producer, who suddenly walks in like nothing happened, and everyone shows up alive later, indicating that the producer "kidnapped them" to add a fear factor on the show. I think the movie wasn't that good anyways, but its ending reminded me of Cry Wolf, and that's why I wanna find it again. Sorry if I lack more details.
I remember that the producer (or at least one of the contestants) had shoulder length black hair, kinda looked like he was indian-ish. There was at least one blonde girl (which horror movie doesn't actually)?
I seem to recollect of a scene where the contestants are eating and drinking on a table (I think it was rounded and white). The scene closely reminds me of a scene from the first season of The Walking Dead, when the characters are dining at the CDC. The surroundings were pretty similar in my mind.
I still could not find this movie, thanks to the popularity of My Little Eye and the related movies being all about serial killers and zombies. IMDb and Tv Tropes were not useful.
Just to emphasize a little more (if that even helps in any way), the strongest points I remember were that:
The only camera watching the group was the one the gay guy was using (and they discover his sexuality after noticing he was always focusing the lens on one of the guys).
There was no true killing in the movie, since at the end all of them showed up alive, like an organized prank to scare off the contestans.
- And I just recalled of a scene with a blonde girl running towards a door, the walls around her with tons of green. I think she was able to escape through that door in a later shot. From the opened door, trees could be seen in a short distance.
