Does Colin have a reputation as a playboy?Lucca definitely assumes that.
Hes described a bit to my dismay as an eligible bachelor.
Hes a guy that has come from money.
Hes a confident guy in the city.
Im not sure if hes very playboy.
Im not saying that thats who Im comparing myself to.
I dont think anyone could fill his shoes in that way.
But JFK, Jr. was seen as this kind of playboy.
For me personally, I explored the lives of Justin Trudeau or the Emanuel brothers.
That kind of powerful.
Theyre gentlemen with full lives.
How did this role come about for you?I wasnt quite sure about the role at first.
I had watchedThe Good Wifethe first couple seasons and obviously, their reputation is stellar.
I heard spinoff and then I also heard theyre launching a new service [CBS All Access].
I didnt know what that meant.
First I went in and I met with everybody.
Living in New York for so long, I know people affected by that scam.
It was easily the most compelling thing that Ive heard in a long time.
