James Flynn, who also worked on The Tudors, told The Hollywood Reporter that he likes finding parallels in historical dramas.
"I think the story is what really excites me," he said. "The amazing thing about The Borgias is it still has contemporary themes.
"It was originally the story that inspired The Godfather, apparently so. I suppose this particular series, for me, is about power and corruption, quite contemporary and yet very appealing."
Flynn suggested that audiences are interested in period dramas for the same reasons.
"All the themes of power, corruption, drama, intrigue, all those elements keep it current," he said. "There's something contemporary about all these dramas that would attract an audience. Not to mention I think there is actually good old-fashioned entertainment in them. There is a matter of escapism as well. Particularly with the current recession and the downturn in feature films."
Flynn's fellow executive producer Neil Jordan has also previously compared the show to The Godfather.
The Borgias airs on Sundays at 10pm on Showtime in the US. The show will be broadcast on Sky Atlantic in the UK.
