jada pinket smith & will smith

*Usually it’s Jada Pinkett Smith talking her marriage to Will Smith.

However, it looks like Mr. Smith’s got something to say about the situation. Actually, he’s got a lot to say, it seems.

So, when it comes to him and Jada and their 20-year stint together and man and wife, Big Willie says the secret recipe to their 20-year relationship is simple: Don’t quit.

ET caught up with the actor as he walked the red carpet at the premiere of his new film, “Concussion,” where he opened up about making his marriage a priority.

“We’ve been married 20 years and we’ve been asking ourselves [what’s the secret to marriage] and really at the end of the day it’s just not quitting,” the 47-year-old actor said of Pinkett Smith, who he first started dating in 1995 and then married two years later. “You can’t expect it to be easy, it’s like our marriage was the most difficult, grueling, excruciating thing that we have ever taken on in our lives. And you know were just not quitters.

“If there is a secret I would say is that we never went into working in our relationship,” he continued. “We only ever worked on ourselves individually, and then presented ourselves to one another better than we were previously.”

Not only did Smith discuss his marriage, he spoke on how his new film, “Concussion,” in which he plays Dr. Bennet Omalu, a forensic neuropathologist, brought a new perspective to him and hit close to home. He says initially he didn’t want to do the film because he’s a “football dad.”

“As a parent, my son played football. I loved it. I watched him,” Smith said. “I had no idea of the long term potential negative impact of repetitive head trauma.”
