I do think there is a degree of male flesh blindness on this thread.
Women (and gay men) like action movies too and some film makers aren't so stupid that they don't notice this.
Men are sexualised in these movies, often as much, if not more than women, especially more so in recent years.
I think you guys just can't see it.
The number of ostensibly heterosexual men who don't realise how campy homoerotic WWE or American Football (Rugby in tights and shoulder pads, clearly that's not remotely gay) is staggering.
The same goes for not noticing male flesh in action movies.
Most male viewers would be thinking that guy must be a strong and fit etc when the straight ladies and the gay guys will be thinking the sort of thing the straight guys and gay girls think when they see a well proportioned lady boob.
The main area in this genre where gender prejudice really kicks in is with age and I think that will eventually change as people become equally ageist towards men and women (the idea of a middle aged man being cast in Doctor Who is almost unthinkable at least to the suits at the BBC now, sadly).
