There are loads of pictures of him on www.gerardbutler.net (4 million hits and counting - I am not alone!)
Same actor, different look.
What's the attraction? Well, for me it's the fact that in real life he is by all accounts both smart (ex-lawyer) and a thoroughly nice guy, both of which are essentials. But when acting he can turn on, at the drop of a hat, an intense, and occasionally threatening, alpha-male physicality.
Just delicious. Sigh...
