Comes across as very cocky.

I don't want to be "that person" but I've recently spent time with Jack, entirely as a fangirl, and he was absolutely lovely. He was humble, if a little embarrassed when offered praise, and was overly generous with his time. He happily discussed past work and upcoming projects, and cracked jokes whilst chatting about football, snooker and Samsung mobile phones. I had the audacity to critique his stab at regional accents and he made a joke about it and said he'd work on it. So yeah, top bloke.

He's a Leo, what do you expect?!

So what if he's a Leo? I'm a Leo. I wondered the same thing as OP. He played such a scumbag in Eden Lake. But it's nice to read he's a nice guy in reality.
