My best friend told me about a movie he saw 10 or 15 years ago. He said it was a predator movie where a group of people are trapped inside a huge invisible force field and are hunted by the predator. I have been trying to find it ever since he told me about it but nobody seems to know anything about it.

Predator lol

The Hunt (2006) ?
IMDb synopsis:
Bow-hunting enthusiast Jack Hamberg, his 8-year old stepson Clint, and former news cameraman Atticus Monroe are on a mission to make a deer hunting video. All that is needed to complete the video is a "kill". Jack and Atticus reluctantly decide to trespass onto a nearby property where there may be more abundant prey. Once inside the restricted area, they come upon some frightening realizations. The hunters have become the hunted. Only one comes out alive with the tapes that captured the horrific events that transpired on the Hunt.

The Hunt (2006) - IMDb (http://www.imdb.com/title/tt0454843/?ref_=fn_al_tt_2)

As I understand it, the government/military are holding aliens captive and allow them to hunt the trespassers.
