How has there not been a good Julius Caesar biopic ? There's the HBO TV show (which is good and more accurate that I thought it'd be, though very condensed), and I'm sure it's been attempted, but it's strange... there are so many potentially great cinematic moments there. The crossing of the Rubicon alone...
Come to think of it, how aren't there dozens of emperor biopics ? Aside from Caligula, the only one I can think of is TV again (I, Claudius). What about Trajan, Marcus Aurelius, Hadrian, Augustus... or freaking Nero, that one practically writes itself !
I guess they must exist but not be very good ? A shame.
