Marvel has a LOT of catching up to do with regards TV Superhero programmes - Other than animated the only one currently I can think of is Agents of S.H.I.E.L.D
It will show up in the UK its a question of what channel, am not if anyone may know but am not 100% sure if there's a CBS channel on Sky if so then maybe it could show up on there.
The only thing i am worried about is Superman does kind of show up but you won't actually see his face now they can get away with this for a while but how long before people get pissed off about that as show carries on and especially with DC/Warner Bros are not keen on Superman or eve Batman showing up on the small screen, apart from that been very impressed with the preview
