bizarre red lights

For this shot I needed a larger depth of field. This gave me a longer exposure. What I didn't know is for exposures 1 sec. or longer sometimes random scattered red light gets in. So on a few stills of the last scene there is a bizarre red light. I did the scene twice before I figured out what caused this. Third times the charm. Shorter exposure. Hopefully everything will still be in focus. I'll post it again once I get it right.
