How director Danny Boyle knew "straight away" that Himesh Patel should be the star of "Yesterday"

The Beatles had 20 number one singles on the Billboard Hot 100 Pop Chart, and they remain one of the most influential bands of all time -- but a new movie, "Yesterday," is set in a world where an aspiring singer named Jack is the only musician who remembers them. Jack becomes famous by pretending the songs are his. Himesh Patel, who plays Jack, joins "CBS This Morning" along with the film's director, Danny Boyle.
