Can men and women be "just friends"?

i think in 90% i does not work out with "best friends" at least. check out this short movie about this: http://www.ilendoo.com/lets-be-friends/

of course.. one of my best friends is a guy.. and he is very good looking but we are very much just friends.

Often the problem, however, is when someone is ONLY friends with someone else because they hope to eventually BOINK them. Often self-proclaimed 'nice guys' (or girls but less of a common occurrence) which buzzfeed cover pretty comprehensively here:
