I simply will not be able to stomach any audio-video representation of Adam Jensen without Elias Toufexis' voice.
To the topic in general: I've always loathed it when people called for the creation of a Deus Ex live action movie (often done in awe after watching the cinematic cg trailers).
Deus Ex is a bastion of video game history; let it remain as such. There is no reason for it to be bastardized into a movie, especially when video-game movies have almost always been horrible detriments to their respective IP's. ಠ_ಠ
