"Fingers crossed, anything is possible in Hollywood, but I think you're going to see Mugatu. We are planning on seeing Mugatu," Justin explained. "There are a couple new villains that step onto the stage, which we are all very happy about. And yes, Jonah is the inspiration for one of them."

So what's the plot look like for the sequel?

"We start off with them in a pretty bad place," Justin said of Zoolander and Hansel. "They're about to ring 40's bell. They have to claw their way back into the fashion industry in some way or another."

But that's all you're going to get! Although, Justin does promise, "It's too funny — it'll blow your mind."
