 The producers cast relatively unknown British actors for the series . Scottish actress Lindsay Duncan , who was cast as Servilia , believed that she and other UK actors " can do old , can do classic , and you believe it . " She also said that because of long distances , American actors or those of other <unk> were avoided : " <unk> actors from [ Los Angeles ] to Rome on a regular basis does not look good for the budget . We 're quite cheap . " Stamp described Servilia as " the great love of [ Julius ] Caesar 's life , his mistress and by all counts the only woman he truly loved . " Irish actor <unk> Hinds was cast as Caesar . Hinds first thought it was " silly " to be offered the part , but then " you think it 's quite an honour to be chosen to play it . And then you think , ' Oh shit I 've got to do it ' , and then , well , ' I suppose someone has to do it ! ' " Heller had believed that Hinds would make " a great Caesar " for a long time , and considered the series " extremely lucky " for being able to cast him .
