I never heard of him before I saw BBM in March of this year.
I was not only impressed with the film as such, but also, particularly, with his performance.
So I started finding out about this guy - and the rest is history

From reading about the films I felt that I didn't want to watch any of them, they all sounded so much like the kind of films I would never go for.
Then Candy came along and I thought, OK, that's a film that's going to be interesting as a film, too. Rented it, liked it.
Then I came to this forum, stumbled onto Planet Heath and was done for....

Now I'm slowly working my way through his films, still somewhat uncomfortable with some.
Next was 10 Things, which I really enjoyed because of its lightness. And as I said, I was surprised to see some Ennis-like facial expressions in Patrick.
Next Casanova, funny and delightful again - I bought the DVD a few days later...
Then Ned Kelly and Sin Eater were shown on TV. (Also Monster's Ball but I made a mistake in programming the video so I never saw it

)
And then The Patriot.
I would like to see Monster's Ball (because his performance there got him shortlisted for the role of Ennis), Four Feathers and a Knight's Tale. Maybe also Lords of Dogtown.
I'm not at all keen on seeing Brother's Grimm.
