Angelina Jolie Takes Her Kids to a Movie

Angelina Jolie's out and about with the kiddos again, and this time they're hitting up the theater.

Ang and 4 of her 6 kids -- Zahara, Shiloh, Vivienne, and Knox -- were seen in L.A. Saturday heading to see a movie together ... flanked by a couple bodyguards.

Not sure what they're seeing, but they've got some good family options with "Hotel Transylvania 3: Summer Vacation," "Christopher Robin" ... or maybe even the hit shark flick "The Meg."

As we reported ... Angelina returned to the U.S. with her children last week after being ordered to do so by a judge in her divorce case with Brad Pitt.

As for the divorce ... it's grown increasingly contentious and hostile the past couple months, so much so that Jolie's lawyer is quitting.

We've also been told Brad's been struggling to maintain a relationship with their 6 kids, with sources claiming she's not helping any.
