20 Films You Didn't Realise Ghostbusters Actors Were In

3. Harold Ramis - Walk Hard: The Dewey Cox Story

Harold Ramis co-wrote the Ghostbusters movies and starred as Egon Spengler - the brains of the titular team and the object of Janine Melnitz's affections - in both movies. But his film credits also include a Yiddish-speaking cameo as the Jewish industrialist L'Chaim in the 2007 comedy Walk Hard: The Dewey Cox Story. Ramis sadly passed away in 2014 and is sorely missed.
