At least Nolan doesn't use the same actor or two for every single movie he does.
Oh yeah? When was the last time he made a movie without Michael Caine?
Michael Caine had a supporting role in The Prestige
and he had a cameo in Inception.
I don't see how that's comparable to Tim Burton, who reuses Johnny Depp and/or Helena Bonham Carter for lead roles in nearly every movie he does.
Also, that's an unfair comparison because Burton has done more movies than Nolan, and it seems like Caine is Nolan's lucky charm, and might appear in every other Nolan movie from hereon in either small or supporting roles, but I don't see how that's comparable to reusing the same main actor or two for every movie in a lead capacity. It would be something if Caine was the lead in The Prestige
but he wasn't.
