7. Donatello: Grant Gustin
Most people are familiar with Grant Gustin from his role on CW’s The Flash, and it is his performance as that character that makes me think he would be the perfect Donatello. The Flash is obviously one of the most popular superheroes of all time, and because of that he is always engaged in some kind of combat.
However, Barry Allen is also a certified genius. It is Grant Gustin’s knack for scientific lingo that makes me think he could pull off Donatello, and I would love to see such a popular television star join the next Teenage Mutant Ninja Turtles film.
