I haven't seen all of Star Trek Into Darkness (2013), but I remember it being discussed as kind of a high water mark for male crying in mainstream genre filmmaking, to the point that some critics were put off by the amount of emotion on display.  (Most notably this curmudgeon: https://www.theguardian.com/commentisfree/2013/may/16/spock-crying-star-trek-into-darkness). 

When I was searching for clips, I also came across this quote from the director, JJ Abrams: "The goal of this movie is to make you cry. If the movie does its job, then by the end of the movie, you will have had a reaction involving the eyes," the filmmaker promised with a laugh. "If the movie works, then there's definitely an emotional component."

I was pretty impressed with all three of these scenes, especially considering the the type of film, and was really pleased to find them online in HD.  I'm still trying to figure out which one I like best.   

The content of all three clips is very spoiler-y

-------------------------

1) A fairly intense crying scene from Chris Pine begins at about 2:35




2) A perfect tear from Benedict Cumberbatch in the last minute or so




3) Pine and Zachary Quinto share an emotional moment + a bonus tear from Simon Pegg
