Replying to What movie am I thinking of?? (It's coming out soon)

This is driving me nuts, i've done a lot of googling and can't find this movie I'm thinking of.

I was watching the movie Captain Phillips in the theater a month or two ago, and before it started there was a preview for an upcoming movie.

The dude wakes up and he's trapped in a room. It almost looks like it's gonna be another Saw movie. He gets fed through a little doggie door and he can't escape. And then he gets older and older, and I think it kind of turns into a sci fi flick.

Anyone have any idea what movie I might be thinking of?

Thanks.
