The initial couple of ‘graphs from a movie-industry blog (and there are no further details after these few words):
Gianni Nunnari and Mark Canton are teaming up with Exclusive Media Group on a potential franchise based on the life of Julius Caesar.
The partners are eyeing a trilogy of films adapted from Conn Iggulden’s four-book The Emperor Series. Exclusive Media Group co-chairman Nigel Sinclair said the company might finance the first project in a split-rights deal with a US studio.

Folks might want to check out an interview with Conn Iggulden from back in 2006 at the UNRV site on this (tip o’ the pileus to Viggen!)

Iggulden’s work covers the lifespan of Caesar, so I wonder if they’ll switch protagonists during the movie or whether they’ll age the actor. Richard Burton wasn’t a bad Caesar when he played him in Cleopatra… I hope they get somebody like him.
*Sorry, meant Rex Harrison.
