Cameo in the Hobbit?

But did we see him anywhere in the first movie? I didn't pick him out.

I think Peter Jackson may cameos as 1 of the ring bearers in Battle of the Five Armies - The plump looking ring bearer who looks a bit like the Jester which PJ dressed up as at Comic Con. It seems highly likely, however nothing has been confirmed.
I wonder if he made any other cameo appearances in the film?

Here is a screenshot of the scene:

... and PJ as Jester at Comic Con:

I hadn't noticed that at all when watching the film but now that you point it out I can't unsee PJ as the jester Ringwraith.

I read an interview with PJ where he was asked about cameos and his only response was to point out that the portraits of Bilbo's parents are based on him and Fran Walsh (which we already knew from the LOTR docs), but he didn't exactly deny having a more traditional cameo...
