Grant Gustin is an American actor, singer, and dancer best known for his role as Barry Allen a.k.a. The Flash on The CW hit series 'The Flash'. He started his journey on television with the series 'Glee', and later was cast as a recurring character in the series '90210' and 'Arrow'. He always dreamed to be a Broadway actor first before foraying into television and films. However, it got flipped as he already got his break on TV, and he joined the Broadway Revival Tour of West Side Story in 2010, six years after his film debut. According to him, the opportunity to work on 'Glee' somewhat fell into his lap as he was not actively looking for it. A prolific tap dancer, he had originally auditioned for a role as a tap dancer in 'Glee'. While he failed to get that part, he did make a mark on Ryan Murphy, the show's co-creator, who remembered him for the recurring role of Sebastian Smythe. Apart from playing the lead role in 'The Flash', Gustin has reprised his role in cross-over episodes of four other television series based on the same fictional universe: 'Arrow', 'Vixen', 'Supergirl' and 'Legends of Tomorrow'.
