The quasi-sequel to the underrated 1995 Robin Williams adventure romp Jumanji is in theaters today. Jake Kasdan's take on the burgeoning franchise is set inside a video game and stars Dwayne Johnson, Kevin Hart, Jack Black, Karen Gillan, Nick Jonas, and more. On Jumanji: Welcome to the Jungle release eve, Johnson and Hart stopped by BBC Radio 1 to eschew the traditional interview format in favor of playfully hurling insults at each other.

Among the delightful turns of phrases exchanged during the nearly four-minute roast war are "nipple head," "titty head," and "buff Urkel." Catch the charming display in full in the video up top.

As for how Johnson landed in Jumani with Hart and the rest of the crew, the Ballers star explained his approach to choosing roles in a recent chat with Variety. "It starts with what's in my gut, and what's in my gut is to entertain as many people as I can possibly entertain," he said. "Generally, they all have this global appeal—they're not all home runs. But the essence of them is that they all have global appeal."

Hart, meanwhile, had to call out a misleading-headline-crafter during a recent Jumanji-promoting interview marathon. After headlines started popping up suggesting that Hart was trying to get a Mrs. Doubtfire reboot rolling, the comedian promptly corrected the story's course:

Good news. Let's leave Mrs. Doubtfire alone, everyone.
