This is the kind of hilarious conversation you get when you put Nicole Kidman, Colin Farrell, Bryan Cranston, and Matt Lucas on the same couch.

The foursome gathered on "The Graham Norton Show" last week, and the conversation turned to Kidman's "Big Little Lies." Graham Norton showed a photo of Kidman kissing her co-star Alexander Skarsgard, who played her character's abusive husband, before he accepted his own award.

"You are so provocative, Graham," Kidman teased, wondering why he showed that photo when "I also kissed my husband, too." Bryan Cranston joked that the photo made it look like Kidman's husband, singer Keith Urban, was applauding the Skarsgard kiss, wanting it to continue.

Kidman laughed through the playful ribbing, saying, "I did kiss [Skarsgard], but you've got to understand, I did everything with Alex." Norton said yes they saw that on screen. Kidman continued, "I've got an amazing, supportive, gorgeous husband who I love more than anything in the world, and I gave Alex a congratulatory kiss, and he's like a mannequin. I mean, not a mannequin." Everyone laughed and the flustered Kidman gave up even trying. "I'm done!"

The conversation then turned to her 50th birthday and the fun she had with her husband, with fireworks and ... "other stuff."

Watch that part of the convo:You may not know Matt Lucas -- he called himself the B-lister of the bunch -- but you should watch him tell some mistaken identity stories in this next video. At one point, he asked Colin Farrell if he were ever mistaken for another celebrity. Farrell said he's often mistaken for Colin Firth -- "who has me by an Oscar and at least 10 inches, and a lot of decorum." He said he tried to sign up for a gym once, and when they went to process his information, he heard one of the employees whispering, "Yeah, Colin Firth is here."

Watch that video: You might as well keep going and watch Bryan Cranston talk about having tunnel sex in the Alps: Just make these exact people go on every talk show together, telling stories and joking around with each other.
