John Cena appeared on Today with Kathie Lee Gifford and Hoda Kotb.
Highlights are below. You can watch the full interview in the video above.
On Jackie Chan
"He's unbelievable. Unbelievable human being, unbelievable professional, and a kind and caring man. I have been a fan of us because I think he's the Charlie Chaplin of our generation; one of the best physical storytellers of all-time. He's exceed any expectations. Not only does he (do his own stunts), he is meticulous. He sees every little detail. He produces (the film), has a hand in writing, and it's almost like he is involved in the creative process of everything. What he really focuses on is telling stories through action. So he and his team completely control all the action."
"I've been a certain character in WWE for 16 years and I've had my hair short. I like to keep short hair. It's easy to manage. The director of this movie asked me to grow my hair out and I'm very self-conscious about my hair. It's very thin and it's running away from me on the top. I figured I'd do it, fine, embrace the uncomfortable. Then I showed up to wrestling with this haircut and it was like I ruined everyone's childhood. I have completely destroyed WWE as a business model. I can never go back to being a normal human. I should walk the streets in shame. It's been awesome as an exercise on how to handle negativity. I laugh at myself and have fun with it. Right now, I'm going to keep it. Just to stoke the fire."
On being vulnerable following his break up with Nikki Bella
"As far as my actions are concerned, that was me being honest and vulnerable. I don't regret it one bit. As far as my personal business is considered, it should remain personal. I don't believe there is any pain in vulnerability, just learning."
The last time Cena appeared on Today, the break up with Nikki was fresh and he opened up about the situation and heartbreak. Cena mentioned that the two ran into each other recently -- they were spotted together in Australia following WWE Super Show-Down -- and things were amicable.
