If you read the full interview he's talking about how demanding it is filming the movies and how exhausting it is coming off the back of it, and the full answer was:
Can you imagine doing another Bond movie?
‘Now? I’d rather break this glass and slash my wrists. No, not at the moment. Not at all. That’s fine. I’m over it at the moment. We’re done. All I want to do is move on.’
You want to move on from Bond for good?
‘I haven’t given it any thought. For at least a year or two, I just don’t want to think about it. I don’t know what the next step is. I’ve no idea. Not because I’m trying to be cagey. Who the feck knows? At the moment, we’ve done it. I’m not in discussion with anybody about anything. If I did another Bond movie, it would only be for the money.’
