 When Woody Allen (qv) cast Jason Biggs (qv), he was under the  impression that Biggs was Jewish. During filming, Allen began  talking to Biggs about the Jewish holiday, Rosh Hashanah. Biggs did  not know what to say and told Allen that he was in fact a Catholic.  Allen said at the Venice Film Festival, "I saw him in that pie movie  (American Pie) and I thought he was a Jew."
