Tip Of My Tongue

I made a vague reference to this movie elsewhere a day or two ago and have been annoyed with myself for not being about to identify it since then. I apologize in advance for the lack of detail. The things I remember:

• The movie is about chosen ones trying to save the universe (I think), found and identified by a similar mentor. Yes, much like Mortal Kombat ... And others.
• Early in the movie, there's a fight scene between the aforementioned mentor and primary antagonist; the fight takes place, I think, in a night club and the antagonist uses telekinesis to direct a spinning vertical CD as a weapon (this is my main memory of the movie).
• The mentor counters the CD attack with his own telekinesis, which holds the "weapon" in place, but then the antagonist endangers bystanders, distracting the mentor, who has to release the CD to save them. He barely dodges the disk and I think gets a cut on his forehead.
• The mentor collects the chosen ones and proves they're chosen by them all having the same birthmark. For some reason this happens on a boat. They all show their birthmarks, other than one who assures them that he has one but it's in a private place. Says something like "you don't want to see it, but trust me, it's there."
• I think the final showdown takes place in a parking structure, but I might be misremembering.
• This one is pure conjecture, but the movie reminds me of eXistenZ. That might be because of any kind of overlap or I might just have seen them in the same timeframe.

Thanks in advance!
