Grant Gustin led nine seasons of The Flash, also playing Barry Allen in multiple other DC series and several Arrowverse crossovers. Even though The Flash season 9 marked the end of the series and the Arrowverse, there are still a lot of fans who want to see Gustin return as The Flash in James Gunn's DC Universe. Gunn has said that he would love to work with Gustin in the future and that, allied to Gustin's excellent run as Barry Allen and his popularity in the role, could lead to the talented actor playing a new Flash in the DCU.
