Piers Morgan at The Daily Mail has created a list of the “100 British Celebrities Who Really Matter.” Robert Pattinson and Michael Sheen are both on the list!

6 ROBERT PATTINSON

This is quite a simple one. Pattinson’s the handsome young star of the Twilight films, beloved of teenage girls and other moody types. That fact makes him a nailed-down cert to be the most sought-after British movie star of 2010.

And that, in turn, makes him ‘matter’. The only problem for Pattinson is that, as my grandmother always likes to say, ‘One day you’re the cock of the walk, the next you’re a feather duster.’ And nowhere is that more true than in good old Tinseltown. So I wish him well, but urge him to watch his back.

And not just because of the millions of girls all over the world who’d like to attach themselves to his shapely shoulders as a matter of urgency.

79 MICHAEL SHEEN

He should be a lot higher on this list, frankly, because Sheen is probably our most successfully versatile thespian at the moment. But he’s not that ‘sexy’, so he doesn’t command the kind of tabloid attention that propels actors from stars to superstars – something that I suspect he’s quite happy about. He’s got one of those Rory Bremner-like faces that can adapt to almost any character, from Tony Blair to David Frost. And he’s a fine, fine actor. So he matters, but not nearly as much as he would if he got caught on a sex tape with Paris Hilton. A tragic, but accurate, state of affairs.
