I just finished watching Juno.
What a pleasant surprise.
There are certain moments in movies when an actor can knock me out...
No lines to speak, the acting is all done with facial expression and body language.
In "Tootsie" Charles Durning amazed me with his expression in the bar scene when he comes to the realization that Tootsie is a man.
Ellen Page has a solo scene with no lines where you know she has made an important decision, and the young actress pulls it off.
Casting is great. Everyone is believable. I liked Jason Bateman, Jennifer Garner was excellent. Michael Cera, an actor I had never seen before, does a wonderful, understated job as Juno's best friend/paramour.
J.K. Simmons, playing Juno's Dad, steals every scene he's in.
I liked it enough that I will again, later.
