Movie where things on people's necks mind control them

Hi, I’m looking for a movie title. (:

Things from that movie:

-There were people mind controlled by something stuck to their necks/heads

-There was a scene where the protagonists walk on a path which stays the same length

-One of the protagonists is an asian guy and knows kung fu

-The protagonists were searching for a girl kidnappen by the bad guys

Thanks in advance (:

Describe device which did the mind control and did it touch both the neck and head?

What year did you see it?

I've changed the thread title to be more descriptive, per the warning beneath the title field:

Closest I can think of is that episode of FMA.

Now you made me think of Babylon 5.
