They're making a Gladiator Two? WTF? Why? How? Let me guess, he knocked up Commodus' sister when she visited him in prison and the kid will be betrayed by the Senate and have to fight its way back into power?
Since everybody knows it's going to be mediocre, they should have just used the budget to make a historically-realistic movie about something in that era.
There's a short 1 season long series called "barbarians" which is supposedly pretty good.
I don't know if they made a session 2, but I know that season 1 had a conclusion and all historic advisors left work for season 2 because it became ridiculous.
