The difference between the big budget films I've done is the length of time. But in terms of the day-to-day, you're still going on to set, you're getting into character, and you're going and doing your job, so there's absolutely no difference. It's just the structure around it and the length of time. But in terms of budget and money, it doesn't really manifest itself.

My first job when I got my equity card was acting in 14 plays back-to-back. Playing that many roles, you look for ways of differentiating the characters physically, which goes hand in hand with understanding them psychologically.

I've done a fair amount of that stuff... when we did Lord of the Rings the transformation sequence from Smeagol to Gollum was a 19-hour make-up job. You have to have a kind of zen button that you press and allow the mind to be focused in a certain way.

I suppose the biggest strain was that Hoodwink is a high-octane character and he's up there like all the time. Once he's on his journey there's no let up for the man, so I actually found it a massively exhausting job to keep that level up.
