Help me find this movie my wife wants to rewatch
A man's friend (work colleague) at the last minute gets him to change his mind to go on a work trip with him and he goes on a coach with all the other work people and when they get there there's like a building and it's not good inside. All weird stuff happens and he wishes he never went. She said it was like the guy who arranged the trip knew what was going to happen.
That's all my wife could give me. She has a strong feeling that someone like Haley Joel Osment was in it, but she hasn't been able to work it out. I tried some searches on this, but none of the results that came back matched. She says it was an American film, but not particularly high budget.
Edit: Thanks to u/nonsense_potter who suggested Rebirth, this is the film she was thinking of!
