It is no secret that one of President Barack Obama‘s favorite television series’ was Entourage. Although the series did come to an end this past summer, it looks like the leader of the free world will be making a cameo when the series hits the big screen in the future. “I promised to make the Entourage movie if he would do a cameo. He agreed. Seriously.,” Adrian Grenier said in aFacebook message which accompanied a photo of the President.
