First shot is in the trailer. 39 seconds in, as Gandalf introduces Gloin.
Main movie, about 2:15 in, the city of Dale is introduced. There is a shot of a map that zooms in on Dale.
The next shot is of the market place of Dale during the 'good times'. The camera follows a girl running through the market place. I am at the back on the left side, talking to a shop keeper about his wonderful selection of birds.
In the next shot, the camera is panning left. This is my big moment. At first only my back and (wonderful) hair are visible.
Then I turn to the right and there is my side profile in all of its glory. The lady in the foreground to the left of me is my character's wife.
At about the 1:28:20 point, the Hobbits have arrived at Rivendale and Elrond is discussing the weapons they have. Bilbo starts to pull out his 'sword' and Balin says, “I wouldn't bother laddie.”
Balin: “Swords are named for the great deeds the do in war.” That is my hand playing some kind of harp in the background.
Bilbo: “What are you saying my sword hasn't seen battle?” My other had in the background.
And lastly, I got a mention in the credits.
