Christopher Nolan's Casio EV-4500 is an inexpensive portable LCD 4-Inch TV everybody can buy for less than $80. The IMAX camera has been modified with an UHF/VHF transmitter and an attached UHF/VHF antenna that allows Christopher to get real time signal preview from the final shot cinematographer Wally Pfister is working on. Fourth photo shows angry Nolan trying to get decent TV signal from the IMAX camera. t: Babe and bike not included So if you are in New York and can get close enough to a filming set don't forget to take a portable UHF/VHF TV with you, if you dial the right channel you could get some TDKR preview shots!!! PS: Please, sticky this thread so people stop asking what is that thing hanging from Nolan's neck.
