They WEREN'T alone, though, as they totes took along three other cast members as well, from the movie they're all working on together called Fury!
The male-bonding activity took place in a desolate forest in Buckinghamshire, England, and we haven't been told whether or not they spent the whole weekend 'practicing kissing' so they'd be better for their lady counterparts when they returned.
Here's the thing, though — this wasn't just some friendly idea one of them came up with! The director actually ordered them to do it!
Here's what the source said about it:
"They play soldiers in the same World War II troop, and the director [David Ayer] wanted to make sure they bonded. So he dropped them in the wilderness — without their cellphones! They must have gotten pretty cozy in the tents they were sharing."
Apparently they foraged for food and also had to endure sub-50 degree temps!
We wonder if it worked!
We'll just have to wait and to see the movie and check out the results for ourselves!
