Yehoram Gaon originally turned down the role of Moshe Weinstok, saying it's too small for someone who hadn't acted for quite a while. He changed his mind after director Joseph Cedar sent him a long list of Hollywood stars who made short appearances in various movies.
Yehoram Gaon's first apperance in the movie comes shortly after a clip from the movie Operation Thunderbolt (1977) is shown - a clip where Yehoram Gaon is giving a speech.
The film is set in 1981 and takes place in the Jerusalem neighborhood of Bayit Va-Gan (per the film's official press kit).
Although the director, Joseph Cedar, was born in New York City, his family moved to Israel, when he was six years old. There, he was raised in the same Jerusalem neighborhood that Campfire is set in (Bayit Va-Gan). As a teenager, many of Cedar's friends moved to Israeli settlements in the West Bank. Unlike the two daughters in "Campfire" though, Cedar was disappointed at the time that his parents never joined the settlements, as he felt felt that it was a chance to take part in something adventurous and historic.
