Mark Cuban joins us this week on The Big Screen to talk about a number of his endeavors: The new Entourage movie, in which he has a cameo (after appearing in several episodes of the TV series); Shark Tank; the upcoming Sharknado 3: Oh Hell No (in which he plays the president), and, of course, the NBA Finals, which he will watch even though his Dallas Mavericks aren't participating.

Cuban is first and foremost a businessman, and Shark Tank reflects his zeal for entrepreneurialism. But he also loves acting, largely because of the challenges involved in learning a new set of skills and exercising a different half of his brain.        

He recalls taking his first acting classes years ago in Los Angeles. "It was the hardest thing I've ever done," he says. "In the real world for me, in business, it's a matter of preparation and control. You want to try and control a situation, make a sale, whatever it may be. In acting you have to use the exact opposite side of your brain and let everything go. It took me a while to just stop worrying about memorizing my lines. But once I started to get it and have fun with it, it's just so different from my normal personality so I like it.

"So anybody out there who's casting, call me."
