Mahershala Ali and Viggo Mortensen Form an Unexpected Friendship in the Green Book Trailer

Are you ready to get emotional? Because the trailer for Green Book, which is based on a true story about two men in the 1960s, is probably going to have you all the way up in your feelings.

The film stars Academy Award winner Mahershala Ali as Dr. Don Shirley, a world-class black pianist, who hires Tony Lip (Academy Award nominee Viggo Mortensen), a Bronx-born bouncer, to drive him on a concert tour that extends from Manhattan to the Deep South. Using the "Green Book," which serves as a guide to the establishments that were safe at the time for African-Americans, the pair form an unexpected bond during their lengthy road trip.

The drama, directed by Peter Farrelly, looks like it combines the perfect amounts of humor and humanity with the harsh realities of living as a black man during that time period (which sadly has more than a little relevance to the state of America today). Watch the trailer above before it hits theaters on Nov. 21.
