In a new short film, ‘Dream Crazy,’ not only does former 49ers and University of Nevada star Colin Kaepernick narrate the latest ‘Just Do It’ spot, he makes an appearance as he continues his theme of sacrificing everything for what you believe.

Along with inspirational professionals, like LeBron James, Serena Williams, Odell Beckham Jr., Eliud Kipchoge, the two-minute film shines the spotlight on incredible athletes, including: 29-year-old basketball phenom and wheelchair athlete Megan Blunk, who took gold in Rio in 2016; Isaiah Bird, who was born without legs, and at 10-years-old has become a force on his wrestling team; Charlie Jabaley, an Ironman who made over his life by dropping 120 pounds, going vegan, and in the process, reversing the growth of a life-long brain tumor; and Michigander Alicia Woollcott, who played linebacker and was named homecoming queen during her high school senior season.

Other emerging professional athletes and world champions alike who make the cut are: Canadian soccer star Alphonso Davies; Hawaiian big wave surfer Kai Lenny; American skateboarders Lacey Baker and Nyjah Huston; German champion boxer Zeina Nassar; and U.S. Soccer's Women’s National Team.

Don’t ask if your dreams are crazy. Ask if they’re crazy enough. #justdoit
