Jeff Goldblum Syndrome

Watching M*A*S*H yesterday made me realise that Alan Alda is one of a select group of actors who have what I like to refer to as 'Jeff Goldblum Syndrome' - the ability to age without it noticeably affecting how they look. With most actors, when you see them in an early role your first remark is usually on the lines of 'wow, is that so-and-so? They look so young' while, when one sees an actor with JGS your reaction is more on the lines of 'oh, that's so-and-so. Bloody hell, they don't look any different - are you sure this was made 30 years ago?'

Goldblum is the most notable of the JGS actors (which is why it's named after him) for not only does he look the same in every role, he's pretty much playing the same role in every one as well. There's hardly any difference between his appearance from the seventies through to today. Other actors with JGS include the aforementioned Alan Alda, Richard E Grant and Steve Martin (though JGS doesn't affect his hair) but I'm sure there are loads of others out there - anyone want to suggest someone?
