It seems that Batman is such a good lip-reader, that he can do it whilst only seeing the person through thermal goggles:
Seems pretty impressive. It just got me wondering though, does Batman often use lip-reading for any reason? I haven't seen him do it anywhere else, but a lot of you will have read a lot more Batman than I have, so I thought I'd ask. I can't seem to find anything online.
Anyone know of any lip-reading by Batman then?
