Last season on The Flash, Barry revealed that his all-time favorite musical is Singin’ In The Rain, which starred Gene Kelly, Donald O’Connor, and the late Debbie Reynolds. Most people around Barry’s age adore hit Broadway musicals such as RENT, Phantom of the Opera, or Les Miserables, but not the Scarlet Speedster. He has fond memories of Reynold’s famous flick because he used to watch it with his mother, so it holds a sentimental value for him.
