shooting via a rear view mirror a person in a car behind

[Wim Vanswijgenhoven]

Hi,

 

I'm looking for the best way to shoot someone in a car behind our camera car via the rear view mirror.

The cars are static at this point so we could work with black cloths etc to lose all reflection etc.

I do want it to look natural and not completely staged but I think that just a polarizer will not do the trick.

 

Any ideas for setups

 

greets
