Karan Johar launched the trailer of his new production Good Newwz with the film's cast, Akshay Kumar, Kareena Kapoor Khan, Diljit Singh and Kiara Advani.

It's a slice of life film with an entertaining plot, and Karan may just have a winner on his hands this Christmas.

Akshay-Kareena and Diljit-Kiara play married couples trying to have a baby.

They resort to IVF but the strangest thing happens next.

The sperms get interchanged!

Of course, the chaos follows soon after.

Good Newwz has been directed by first-timer Raj Mehta.

This is, in fact, Akshay's 23rd film with a debutant director.

'Personally, I find the spelling rather ridiculous,' Karan says, referring to the film's title.

"I wanted to make a social comedy," Karan said at the launch.

"Dharma Productions hasn’t made it yet. So when I went to Akshay, I went with a badi script because he’s a mega movie star. But Akshay has a speciality. He searches for content; he doesn’t look at the scale or director. He’s the only superstar, who has worked with so many debut directors."

He tells us more in this video below:

Kareena was the first to come on board while Kiara was the last.

Good Newwz will release on December 27.
