Yeah, and they needed that key scene to set up Catching Fire, since Peeta starts acting coolly/ formal around Katniss off camera and keeps his distance from her in the beginning because of the end scene in THG.

His whole attitude towards her in the second movie will only make sense to those of us who have read the books. :P
