The one in Riddick was somehow so obvious i feel its almost like they wanted us nerds to react!
Knowing that Vin Diesel is himself a gamer, both computer games and PnP rpgs and by all definitions a nerd, it wouldn't surprise me =)
Btw, I didn't find this one any good. I do like Vin Diesel (usuly and ESPECIALLY ad Riddick) and i really like both Pitch Black and Chronicles of Riddick. But this one felt like they where forced to push out another one without any passion.
Might be I just expected too much, i dunno.
