Though his father was Jewish, actor Kevin Kline is not a Jew. Wikipedia reports, "Kline's father was Jewish, from a family that had emigrated from Germany; Kline's mother was of Irish descent, the daughter of an emigrant from County Louth. Kline was raised in his mother's Catholic religion (his father had become an agnostic)... He graduated from the Catholic Saint Louis Priory School in 1965."
In the controversial new film, The Last of Robin Hood Kline plays Errol Flynn (who was not Jewish). The movie recounts Flynn's last scandalous affair with young underaged girl - Beverly Elaine Aadland - and has received some criticism and negative reviews because of that pedophilic theme.
