Warning: The following contains some SPOILERS for Gladiator II!A historian is pointing out one historical error in the shark naval battle in Ridley Scott’s Gladiator II. The sequel to Ridley Scott’s 2000 epic follows Maximus’ son, Lucius Verus (Paul Mescal), as he steps back into the gladiator arena after Rome invades his home city, Numidia, under the rule of twin emperors, Geta (Joseph Quinn) and Caracalla (Fred Hechinger). The naval battle is a cruel form of entertainment that fills the Colosseum floor with water and tiger sharks while re-enacting a naval warfare with fighters from two boats fighting each other to death.
