I was watching Kate and Leopold again recently I had seen it years ago on TV, but really watching it again, there is a strong gay vibe coming off the scenes between Hugh Jackman and Liev Schreiber. Indeed, had the producers went with that chemistry they had, this film would have been more memorable and quite fun. I know that Hugh and Liev starred together in that Wolverine film but I never gleaned any kind of sexual tension there.
So, that's the whole point of this thread:
Name a movie with something similar along those lines.
