Some more on my favourite TOS character on Trekmovie.com:

At the Empire Awards in London on Sunday, Empire Online tracked down Simon
Pegg (the new Scotty) and put the screws to him to get him to talk a about
the super-secret Star Trek. Pegg kept mum about plot details, but did say he
was finished shooting except for "some effects stuff" and that he though the
film is "going to be fantastic." He also talked about his predecessor and
geeking out on set.

Pegg on the original Scotty:
Everything is just a tribute to James Doohan and it's his role. I'm just
very honoured to be able to step into his shoes. I just hope I do him proud

On his favourite moment, 'as a Star Trek geek':
Just being there on the Enterprise, it was incredible. You're going to love
it.
