Thanks to on demand cable, we get to see a wider range of movies at Chez Angus than what shows in the local multiplex (though with a lag of course). We just watched "Lars and the Real Girl" and I have to say based on his performance there and in "Half Nelson" that Ryan Gosling is an incredibly talented actor. Both movies required his character to do really strange things and he was amazingly believable and compelling at all times.
On the face of it, the plot of "Lars" is untenable, but Gosling (along with the actors playing his sister-in-law and his doctor) really pulls it off. If you haven't seen it, you should (Half Nelson too!).
My favorite actor used to be Guy Pierce, but while "Memento" is a better movie than any in which Gosling has appeared, I gotta give Ryan the nod at this point (Guy will no doubt be devastated to hear this news).
