Peter Capaldi was nervous about 'Doctor Who' having an affect on his personal life.
The star - who will make his first full appearance as the new Time Lord tonight (23.08.14) - admitted he had to think "carefully" about the offer to follow Matt Smith in the lead role, but the positives far outweighed the negatives.
He told The Sun newspaper's TV Magazine: "You have to think about that offer carefully because you certainly become more visible, which is a different experience. My life prior to 'Doctor Who' was very blessed already.
"I had to think about whether I wanted to change that and take on the big changes the show might bring ... My life has changed completely in the last year, but that's sort of way you become an actor - so you don't go to the same office every day for 50 years."
One special moment for Peter was seeing an action figure of himself, and he admitted the thought of being "the guy who said no to 'Doctor Who'" meant he had to accept the role.
He said: "I saw it last week - it's good. It's very strange to see yourself at that size - pocket-sized Pete!
"At the end of the day, how can you say no to 'Doctor Who'? Do you want to be the guy who said no to 'Doctor Who'?
"For the rest of your life? Do you want to walk around watching the other Doctor?"
