Now, That's a Working Bromance

Simon Pegg and Nick Frost are making it work:
Slate: Your movies seem to privilege your friendship with Nick—or whatever character he's playing—over romantic love. Why do you think that is?
Pegg: Nick and I always talk about it, it's always played up, this idea of bromance, when really, when women are like that with each other, it's not commented on. Whereas with guys, it's still weird if guys are kind of affectionate with each other, and I just find that really interesting because it comes from guys being very uptight and homophobic. With Hot Fuzz, there was definitely a homoerotic subtext, when the guys are fighting in the rain with their tops off. With Paul it was kind of more the fact that they'd become almost co-dependent and couldn't function outside their own relationship. But if Nick and I are doing the film together, it has to be about that. There was a female character in Hot Fuzz initially called Victoria who ran the local bed and breakfast and who Angel had a relationship with. But it felt really tacked on, like we were only doing it to play lip service to that, when really, what that film is about is the romance between Danny and Nick. 
Does it help if they're British, though? Could two Americans do this sort of thing? Bear in mind your only two choices are Adam Sandler and Kevin James OR Simon and Garfunkel.
