It's not unusual for co-stars to get close while working on a movie together, but Henry Cavill and Armie Hammer have taken it to a whole new level.

The friendship that the two actors formed while working on "The Man from U.N.C.L.E." has blossomed into a full-on bromance, and honestly, we're a little worried about how Henry and Armie are gonna handle it when they have to go their separate ways. Can these guys even exist without each other?

Check out our roundup of pics before you decide.

It all started with scenes like this one, in which Henry and Armie shared a tiny scooter.

Now that the movie is over, they just want to keep the closeness going.

No, closer.

There. Perfect.

Neither of these guys ever looks so happy as when he's got an arm draped over his best bro's shoulder.

Sometimes, Henry gazes at Armie with such love, it'll melt your damn heart.

And when they're forced to separate, the space between them fills with unspoken yearning.

This distance cannot be tolerated.

THERE. Never let go! [Gross sobbing.]
