During Season 3 of Legends of Tomorrow, the crew of the Waverider will travel throughout history to fix multiple aberrations and anachronisms in time. When the show resumes this fall, the Legends will travel from present day 2017 to Ancient Rome. When in Rome, the Legends will run into none other than the infamous Julius Caesar.

CBR has confirmed that Julius Caesar will be played by actor Simon Merrells. Speaking with the press at Comic-Con International, Legends of Tomorrow executive producer Phil Klemmer shared this exciting casting news. "We start out in 2017, obviously," said Klemmer, "but we’re going to take a trip back to Ancient Rome. We’re going to have Simon Merrells -- he played Julius Ceaser's [patron Crassus] on Spartacus -- who’s going to be playing Julius Ceasar on our show."

Merrells previously starred on The CW's The Tomorrow People with The Flash's Robbie Amell. Marrells is also the sixth Spartacus actor to join the Arrowverse, which includes Manu Bennett, Todd Lasance, Liam McIntyre, Nick Tarabay, and Katrina Law. Merrells also previously held roles on the History Channel's Knightfall and SyFy's Dominion.

Legends of Tomorrow returns to The CW this Fall, on Tuesday, October 10 at 9PM.
