During the film’s production, there were unconfirmed reports and alleged set photos that suggested The Celtic Warrior was cast in the sequel to one of 2014’s biggest blockbusters. However, his involvement was never official until now. Will he be transformed into the mutant rhinoceros hooligan alongside Bebop? We certainly have our fingers crossed.

Sheamus joins an all-star cast, including Megan Fox, Will Arnett, Tyler Perry, Brian Tee and  SummerSlam 2015 competitor Stephen Amell – not to mention Leonardo, Donatello, Michelangelo and Raphael. “TMNT 2” strikes in theaters June 3, 2016.
