Now to action hero and comedian terry crews about to try something new taking over "Who wants to be a millionaire." He flexed his new game show muscles. Reporter: He won us over on the big screen. I got the shakes that will make you quake. Reporter: Made us laugh on our home screen. Calling them doodles is an ins insult. Reporter: Showed us his power and spice. Now funny man terry crews is taking over daytime television in yet another role, host. Let's play "Millionaire." You know, my thing is always every day I have to do something I'm scared of and all of a sudden you are doing things you never thought you would do. I never thought I would be hosting a show. Reporter: But he is. And 15 years after he wants to be a millionaire debuted he is joining the list of legends who hosted the iconic show. I'm guessing you'll see a lot of laughs. You'll see lots of this. Lots of this. Terry crews takes on the game show. A lot of T & a involved right now. I'm talking about the explosion kind. For me I'm explosive. So what I'm saying it's going to be a mix of old spice meets "Expendables" meets the game somehow. Pow! Reporter: He clearly brings his love of life and humor on set but the million dollar question. No one has won a million dollars since 2009. Is it going to happen on your watch? I think so. I'm on their side. I am trying to give away ABC's money. Every day over a million ABC says -- It's out of your pocket. It's going to be millionaire. Reporter: Since I was there on set he put me in the hot seat and, oh, boy. Are you ready to play "Millionaire"? Yes. Here you go, Sara.
