Don’t have HBO and thought that meant you had to illegally download skip the “Game of Thrones” Season 6 premiere? Nonsense! HBO and Cinemax just announced a Free Preview Weekend from Friday, April 22 to Monday, April 25. That means you’ll get to see (if you want to, anyway) the new premieres for “Game of Thrones,” “Silicon Valley,” and “Veep,” plus the pay-TV premiere of “Jurassic World.” Oh, and Beyoncé. Her Saturday night special event. You can watch and see how Twitter reacts.
